ABSTRACT
By using a nonlinear computer analysis, a parametric study is developed in
order to examine the accuracy of the Moment Magnifier Method of the American
Concrete Institute Code (ACI 318-83). The variables used in the parametric study
are: axial load intensity, P/P0\ column reinforcement ratio, p; slenderness ratio,
klu/r\ shape of column cross section, flexural stiffness ratio, and distribution of
axial loads. In the parametric study, 216 cases of single bay fixed-base portal frames
are examined. The higher moment for each one of these frames at failure are then
compared with the design moment predicted by the Moment Magnifier Method of
the American Concret Institute Code (ACI 318-83).
The Moment Magnifier Method proved to be very conservative when the
columns are subjected to high level of axial loads and when the slenderness ratio is
increased.

CHAPTER 1
Introduction
The complex problem of the behavior of slender reinforced concrete columns
in unbraced framed structures has been the subject of increasing investigations in
recent years. The analysis of such structures should take into account the influence
of axial loads, effects of deflections on moments and forces, the development of
cracks in the concrete, and the effects of duration of loads. When such analysis
is not available, the American Concrete Institute Code (ACI 318-83) recommends
the Moment Magnifier Method for the design of reinforced concrete frames with
slenderness ratio, klu/r, no greater than 100. Even though this approximate method
provides a relatively easy way to design these structures, some studies have found
the Moment Magnifier Method to be inaccurate and too conservative in some cases.
The purpose of this study is to analyze the accuracy of the Moment Magnifier
Method. This is done by developing a parametric study on some of the variables
affecting the behavior of unbraced reinforced concrete frames, using a nonlinear
computer analysis, and then comparing these analytical results with the predic
tions from the Moment Magnifier Method of the American Concrete Institute Code
(ACI 318 -83).
The need for a more accurate analysis that reflects the different factors in
fluencing the behavior of slender reinforced concrete structures has motivated the
14
development of experimental and analytical research. Some of this research is re
viewed in Chapter 2. Chapter 3 presents and explains some features of the computer
program, FPIER (Poston et al. , 1983), used in the analysis. Chapter 4 presents the
variables chosen for the parametric study and the way it was carried out. Chapter
5 discusses the results obtained. Chapter 6 provides the conclusions from the study.
Finally, Appendix A presents the listing of the program FPIER, and Appendix B
presents a sample input and output of the program.

CHAPTER 2
Literature Review
2.1 General
Experimental and analytical research on the behavior of slender compres
sion members have been the focus of many researchers over the last two or three
decades. Many of the researchers have based their analysis on a column as an iso
lated frame member, such as Broms and Viest, who, in 1958, developed theoretical
analysis for the ultimate strength of long hinged and long restrained reinforced con
crete columns. They also developed a design procedure for long reinforced concrete
columns based on the strength of a short column, the eccentricity determined from
an elastic analysis, and a reduction coefficient. They showed that the ratio of the
strength of a long column to that of a short column depends primarily on the slen-
derness ratio and on the ratio of end eccentricities. Chang and Ferguson, 1963, also
developed theoretical analysis for both eccentrically and concentrically loaded, long
reinforced concrete columns under short-time load.
Saenz et al., 1963, suggested a Rankine type formula, = 1+00^l_6^ j
for practical design of short, intermediate and long columns, where P0 is the ul
timate axial load on a column with slenderness ratio equal to or less than 15; P'u
is the ultimate axial load on column with slenderness ratio greater than 15; L is
the unsupported length of the column, and t is the least dimension of the trans
verse section. This formula was developed from test results of 52 concrete columns
with rectangular sections having longitudinal reinforcement with ties and flat ends
with slenderness ratios varying from 21.6 to 43. Pfrang and Siess, 1964, studied
the behavior of long eccentrically loaded reinforced concrete columns with rota
tional restraints at their ends. The parameters investigated were: the ratio of end
eccentricities, eccentricity of load, degree of end restraint, and slenderness ratio.
They concluded that decreasing the ratio of end eccentricities effectively increases
the stiffness of a column, and therefore increases the capacity of em unrestrained
column. It was shown that an increase in the eccentricity of load always decreases
the column capacity, and that an increase of the coefficient of end restraint always
increases the capacity of a given column. Finally, they found that an increase in
the slenderness ratio of unrestrained columns increases the deflections and therefore
reduces the column capacity.
In more recent years, increasing interest has been paid to the interaction of
columns and beams as part of a frame. Studies of entire frame interaction included
a series of rectangular frames tested by Breen and Ferguson, 1964. They tested five
frames with long tied columns under short-time loading, and one frame under 90 day
sustained load. They concluded that there was no long column strength reduction at
a nominal eccentricity of 0.3 of the column thickness. They also concluded that when
the eccentricity is equal to 0.1 of the column thickness, there was no long column
strength reduction at a slenderness ratio, of 15; however, at an ^ of 30 there was
a three percent reduction for one specimen and eight percent for another, where h
is the unsupported length of a column, and t is the overall depth of a rectangular
17
section in the direction of bending. Using a computer analysis, Pagay et al., 1970,
examined the behavior of column and beam up to failure in unbraced frames under
lateral and vertical loads and in braced frames with columns bent in single curvature.
As a result of the analysis, they found that the steel ratio in the beams of braced
and unbraced frames is one of the most important variables affecting the column
strength. Columns restrained by beams with minimum reinforcement failed under
low loads. The strength of columns restrained by beams with heavy reinforcement
was greatly increased.
The analysis of slender reinforced concrete frames presents some difficulties
due to the nonlinearities arising from the stress-strain relationships of the materi
als, the development of cracks in the concrete, and the secondary load- deflection or
P- A effects. These difficulties are recognized in the current design code recommen
dations, which encourage a complete non-linear analysis of the entire structure. In
the year 1977, MacGregor and Hage examined procedures for carrying out second
order analysis. They also examined the use of second-order analysis in the design of
concrete structures, and presented a procedure for the design of columns. With the
advances in computer numerical techniques and concrete stress-strain relationships
some researchers have developed analytical models to consider a greater range of
parameters affecting the behavior of reinforced concrete frames. The results from
these models are frequently compared with test results of similar structures. Once
their validity is proven, a parametric study can be made.
The Moment Magnifier Method of the American Concrete Institute Code
(ACI 318-83) is presented in this chapter, together with some recent research per
formed with the purpose of finding new approaches that take into account the
18
non-linearities mentioned above.
2.2 Moment Magnifier Method
The American Concrete Institute Code's approach to frame design consists
of determining the effects of loads, using simple elastic theory, then modifying the
calculated forces to include second order effects. The approximate evaluation of
slenderness effects, based on the moment magnified, can be made if the slenderness
ratio is less than 100.
For an unbraced frame, the ACI 318-83 new magnifier equation expresses
the column secondary moments separately as the sum of the magnification due to
essentially nonsway moments or gravity load effects, plus the magnification due to
sway moments or lateral load effects, (Notes on ACI 318-83, 1984). This can be
expressed by:
The term S^Mib is the magnified gravity load moments due to the effects of member
curvature only; where £(, is a braced frame magnifier,
Mc = 6bM2b + (2.1)
(2.2)
and,
P EI
* ~ (W„)2 (2.3)
where:
Pu = factored axial load
19
(f> = strength reduction factor
Pcb = critical load computed for a braced condition
EI = flexural stiffness of compression member
kb = effective length factor for compression member equal to
1.0 or less, and determined using alignment charts
lu = unsupported length of compression member
The term Cm in equation 2.2 is an equivalent uniform moment factor given
but not less than 0.4 for braced conditions with no transverse loads between the
supports.
Mn and M2t are the smaller and larger factored end moment on compression
member due to loads that result in no appreciable sidesway, respectively. Both are
if the member is bent in single curvature, and negative if bent in double curvature.
The second term of equation 2.1 is the magnified lateral load moments due
to effects of lateral drift; where 8, is sway frame magnifier,
by:
(2.4)
calculated by conventional elastic frame analysis. The ratio is taken as positive
(2.5)
and,
p *'EI
(W2 (2.6)
20
where:
Pcs = critical load computed for an unbraced condition
ks = effective length factor for compression member
greater than 1.0, and determined using alignment charts
The symbol S in equation 2.5 indicates the summation for all columns within
a story.
When equation 2.1 is applied for design of columns of a frame not braced
against sidesway, both terms of equation 2.1 must be evaluated. M2b is the larger
end moment due to gravity load and M2„ is the moment on the column resulting
from lateral load effects. Both moments, M2& and Mia, are computed using a
conventional first order frame analysis.
The member stiffness, EI, used in equations 2.3 and 2.6 is the major pa
rameter and as a consequence the accuracy of the Moment Magnifier Method is
highly dependent on the value used. The stiffness parameter EI must reflect the
nonlinearity of the concrete stress-strain curve, the degree of cracking, and creep.
In lieu of a more accurate calculation of EI, the ACI 318-83 code suggests
the following equations:
EI = + E.I,e 0
(2.7)
or conservatively:
(2.S)
21
where:
Ec = modulus of elasticity of concrete
Ig = moment of inertia of gross concrete section about
centroidal axis, neglecting reinforcement
E„ = modulus of elasticity of the reinforcement
I,e = moment of inertia of reinforcement about centroidal
axis of member cross section
2.3 Review of Recent Investigations
MacKinnon developed a computer program, STR3, in 1980, to determine
the overall frame behavior. The program uses an elastic-plastic force-deformation
relationship and second order effects are included using stability functions. The
inelastic rotation of the hinge is treated as a degree of freedom and the plastic
moment capacity as a known force. The primary advantage of the method is that the
inelastic rotation of the plastic hinge is immediately available once the equilibrium
equations are solved. The main limitation is that when plastic hinges are present,
the loading configuration is limited to nodal point forces.
STR3 was used to model the behavior of frames tested by Ford in 1977. This
study concluded that realistic deflections can be obtained if the column stiffness is
calculated by:
EI = EcIg( 0.2 + 1.2 ptn) (2.9)
and if the stiffness of the beams are calculated by:
EI = QAEcIg (2.10)
22
in weak beam system, or by:
EI = Q.6EcIg (2.11)
in strong beam system, where:
Ec — modulus of elasticity of concrete
Ig = moment of inertia of gross uncracked section
pt = ratio of total reinforcement to gross area of section
n = ratio of modulus of elasticity of reinforcement to
modulus of elasticity of concrete
MacKinnon suggests that the ultimate load carrying capacity of reinforced
concrete frames can be found by using the Mechanism. Curve Method. The point
of intersection of the curve of second order rigid plastic behavior and the curve of
second order elastic-plastic behavior represents an approximation of the ultimate
capacity of the frame (see Fig. 2.1).
MacKinnon also developed a design method for ail unbraced reinforced con
crete frame subjected to both vertical and lateral loads. The design method uses
the Sway Index Method and it is summarized in the following steps:
1. Determine the vertical and lateral forces at each story based on expected use.
2. Establish the framing geometry and select preliminary member sizes.
3. Conduct a first order elastic analysis using appropriate load factors, load
combination factors and live load reduction factors.
The member stiffness can be calculated using equations 2.9, 2.10, and 2.11
when actual P-M-$ relationships axe not available.

4. Determine stability index, Q, for each floor. For multistory frames, Q may be
determined using:
SPm'(AUt Au(,-i)) **' ~ TJ I (2.12)
where EPU, is the summation of the factored axial forces in the columns of the
ith floor, (Aut- — Au(i_!)) is the interstory sway and Hu{ is the factored lateral
load at the top of the floor, and /,• is the story height.
5. If Q < 0.04 at each floor go to step 10.
When Q < 0.04, the P-A effects resulting from sway should be less than 5
percent of the first order moments and the frame can be considered to be
braced.
6. If Q < 0.20, compute the P-A deflections at each floor using:
where A2j is the second order lateral deflection of the ith floor. For Q > 0.2,
a more refined second order analysis should be used.
7. Compute the additional shear resulting from A2|- using:
8. Determine the modified lateral force, H'u, at the top of each floor where:

H'U=HU + (F/+1 - VI) (2.15)
9. Conduct a first order analysis using H'u values and check that resulting lateral
sways are within 5 percent of those used to calculate the V( values.
10. Design columns.
Although the analysis includes second order effects, the maximum moment
may occur within the length of the column and not at the ends. To check if
the maximum moment occurs at the ends the following condition should be
verified.

Poston et al., 1983, developed a computer program, PIER, based on the
fiber model (Adams, 1973). PIER analyzes a single column bridge pier subjected to
biaxial static loads. One of the main advantages of the fiber model is the versatil
ity to handle different types of cross section shapes and longitudinal configurations
such as tapered and flared. In the fiber model, the pier is divided into a number
of segments along the length of the member and the segments are divided into a
number of sections. The sections are then divided into fibers (see Fig. 2.2). PIER
analyzes columns with rectangular solid, rectangular hollow, rectangular cellular,
circular solid, circular hollow, and oval cross sections. The load acting on the struc
ture is applied in increments. Incremental displacements and forces are calculated
for each incremental load and added to the previous displacements and forces to
obtain their new values. The stiffness method is used to calculate the incremental
displacements from the applied loads, and the incremental forces are then computed
from the displacements.
The principal assumption of the method is that small changes in displacement
can be linearly related to small changes in force, and plane sections before bending
remains plane after bending. The linear formulation was modified to take into
account some nonlinear effects such as those due to second-order deflection effects
(P-A), geometric nonlinearity, and material nonlinearity.
The corrections for P-A effects are applied to the member stiffness matrix
and they represent the required corrections to satisfy equilibrium in the deformed
position. To account for diange in geometry effects, the joint coordinates of each
segments of the pier are changed at every increment. The joint displacements are
calculated and added to the previous coordinate at every step, and a new set of

rotation matrices and lengths are computed for each segment of the pier. The
material nonlinearity is handled by using a tangent stiffness for a strain of a given
fiber. In order to determine the tangent stiffness of a given value of strain, a function
of stress-strain relationship of that particular type of fiber is used. The value of a
strain is entered into the function and the slope at that point or the first derivative
of that function is the tangent stiffness, (see Fig. 2.3).
The tensile strength of concrete is neglected; however, the influence of the
concrete around the bars under tension is considered. This is done by using the
mean strain along the bars. The program uses the following expression to compute
the mean steel strain for p > 0.5%:
e m = e , -^r (2 . IS) P&3
and for p < 0.5%,

where:

K' — coefficient to calculate correction in steel strain,

p = steel percentage ratio
E, = steel modulus of elasticity
The stress is found by multiplying the strain, calculated from previous equa-
30
tions, by the modulus of the steel. If the computed stress exceeds the yield stress,
the stress is taken as the yield stress. PIER arbitrarily considers fracture in the
steel if a fiber strain reaches 1%. Fig. 2.4 shows a family of curves with different
steel percentages for a yield stress of 40 ksi calculated by using equations 2.18 and
Two different concrete stress-strain curves are used; one for unconfined con
crete (see Fig. 2.5) and one for confined concrete (see Fig. 2.6).
The effect of load duration or sustained load effects on the pier is considered
by using a modification of the short-time stress-strain relationship for concrete. A
procedure suggested by Chovichien et al. (1973) is used. The modification consists
of expressing the maximum compressive stress for concrete and the concrete strain
corresponding to maximum stress in terms of logarithmic function of time. The
expressions used in the program are:

which is equal to 0.0038 when no time effects are considered. Comparisons were
made with test results and the computer program and were found to be in agreement
with each other (Gilliam et al. 1983).
Poston et al. also developed an extension of program PIER called FPIER.
The program, FPIER, analyzes rectangular frames with symmetrical configurations
of up to two bays and three stories. As program PIER does, FPIER also manipulates
a diversity of cross section shapes and variations along the member axis.
The loading is assumed static and monotonic and it is applied in increments.
The fiber model is also used in the program FPIER. Each member of the frame
is divided into a specified number of longitudinal segments. Each segment is then
divided into a number of equal sections for purposes of computing the stiffness
matrix of the segment. When the segment stiffness matrix is calculated, it is used to
assemble the member stiffness matrix which is then rotated into global coordinates
and added to the frame stiffness matrix. The stiffness matrix is gathered for every
load increment and the cyclic process is repeated until all increments of load have
been applied to the structure or until failure occurs. The failure occurs when there
is material failure, or when a negative stiffness occurs signalling a plastic hinge
formation or when there has been a stability failure. The program assumed a
concrete compression failure if any fiber strain exceeds the specified ultimate strain
of concrete, and a tensile failure is assumed if any steel fiber strain exceeds 1%.
All nonlinear effects are included in the formulation and they follow the same
35
approach used in program PIER. Program FPIER was checked against a number of
frame results. The analytical predictions were in good agreement with experimental
data up to the development of full plastic hinging (Gilliam et al. , 1983).
In 1984, Diaz developed a computer program to analyze the stability effects
on typical frames. The program is based on a complex fiber model. Diaz uses the
word complex to differentiate his formulation from the fiber model used by Poston
et al. which also accounts for all nonlinear effects, but uses some approximations to
generate the effects of nonlinear geometry. In the complex fiber model, the nonlin
ear effects are all already included in the formulation and therefore no modifications
are required. In fact, Diaz compared several experimental load-deformation frame
responses with the complex fiber model and the fiber model predictions. He found
that in all cases the ultimate capacity was very well predicted by both the fiber
model and the complex fiber model, even though there were some discrepancies
between the analytical and the experimental load-deformation curves. Diaz consid
ered that the load-deformation behavior is predicted better by the complex fiber
model particularly close to the ultimate capacity of the frame.
The program uses a tangent stiffness formulation and it is based on large
deformation theory. Each member of the frame is divided into segments, which can
be of unequal lengths and can have different types of cross sections. Each cross
section is subdivided into fibers to obtain the stiffness matrix of the member. The
loading is assumed to be static and monotonic, and the desired load for the structure
is applied in increments.
To account for material nonlinearities, an elasto-plastic model for the steel, a
Hognestad stress-strain curve (Hognestad,1951) for unconfined concrete, and a Ford
36
stress-strain curve (Ford,1977) for confined concrete, are used in the formulation.
Diaz studied the behavior of a number of frames subjected to combination of
vertical, and lateral loads. Comparisons were made between the numerical results
and those of approximate methods, such as the Moment Magnifier (current ACI code
approach), the Additional Moment Method (current CEB/FIB code approach) and
the Stability Index Method. The comparisons were accomplished in two different
ways. The first way compared the predicted analytical moments with the design
moments from the approximate methods mentioned previously. The second way
compared the predicted analytical capacity of each frame with the design capacity
obtained from the approximate methods.
From this study, Diaz concluded that the three approximate methods pre
dicted reasonable values of design moments for the cases having symmetrical axial
loads. The Moment Magnifier and the Q-Index method tend to underestimate the
moments when the axial loads are unsymmetrically distributed. However, the Ad
ditional Moment Method (CEB/FIB) gave reasonable estimates of the moments for
cases of story columns not having the same axial loads.
From the comparisons of predicted capacity, the Additional Moment Method
was found to be very conservative for both symmetrically and unsymmetrically ap
plied axial loads. The method becomes more conservative when the axial load in
creases. The Moment Magnifier (ACI 318-83) and the Q-Index method predicted
similar capacities. Both were conservative, up to 20%, for the case of symmetrically
applied axial loads. In the case of unsymmetrically applied axial loads, both meth
ods showed a zone where the results were slightly unconservative, by no more than
10%.

CHAPTER 3
Computer Program FPIER
Some general features about the formulation of program FPIER (Poston
et al., 1983), was presented in the previous chapter. FPIER is based on the fiber
model. Its primary objective is the structural analysis of reinforced concrete frames.
It handles the member cross sections shown in Fig. 3.1. FPIER can also treat
assemblage of straight, tapered, or flared columns.
The main assumption in the formulation of program FPIER is that small
changes in displacement can be linearly related to small changes in force, and that
plane sections before bending remains plane after bending. The main limitations
are that the frame must be rectangular and geometrically symmetrical in elevation
with a maximum of two bays and three levels.
The program input can be summarized in five major areas:
• Geometry of the structure
• Member properties
• Boundary conditions
• Information about the segments required
• Loading systems

The geometry of the frame is specified by giving the number of column lines,
number of levels, height of columns at each level, and the span of each bay.
The member properties are specified in terms of the type and geometry of
each member section, description of the distribution of steel reinforcement and con
crete cover. It also requires material properties, such as the compressive cylinder
strength of concrete, f'c, the yield stress of reinforcing steel, fy, the strength re
duction factor for concrete, the initial modulus of concrete, Ec, the modulus of
reinforcing steel, Ea, the ultimate strain of concrete,eu, and the creep factor, /?.
All nodes are assumed to be free to translate and rotate unless the boundary
conditions are specified to impose translational and/or rotational restraint. Any
prescribed displacement may be specified at supports.
The program requires information about the number and lengths of segments
desired for the members of the frame. The maximum number of segments in the
entire structure is 150 (10 segments for each of 15 members). The number of
segments should not be less than 5 for columns, and 3 for beams.
Loads are restricted to nodal points which axe the joints between members
or joints between segments. Distributed loads must be input in terms of statically
equivalent concentrated joint loads. Point forces and moments must be resolved
into the major axis of the global coordinate system.
There can be as many load cases and load increments for each case as desired
to predict the frame behavior. The incremental loading is applied in the number
of increments specified for that load case. If another load case is desired, the new
loading and number of increments are specified. The new incremental displacements
and incremental forces are added algebraically to the displacements and forces of
the previous loading for other load cases.
The output from FPIER consists of the printout of incremental results that
includes displacements and rotations at each joint, and the forces and moments at
the end of each segment for each member. The analysis is finished when the load
increments have been completed, when there is an assumed material or stability fail
ure, or when a negative stiffness occurs signalling a plastic hinge formation. When
the frame undergoes any of these types of failures, the displacements and forces,
for the last increment before failure, are printed. A listing of the program, FPIER,
and a sample input/output are presented in Appendix A and B, respectively.

CHAPTER 4
Parametric Study
MacGregor, 1970, suggested that the following variables have the most effect
on the strength and behavior of slender columns: slenderness ratio, l/h; shape of
cross section and reinforcement position; reinforcement ratio, pt] ratio of distance
between the outer reinforcement layers and the overall thickness, 7; and eccentricity,
e/h. MacGregor also performed studies on the interaction of columns and beams in
a slender unbraced frame. He suggested that an increase in the degree of rotational
restraint at the ends of the columns by increasing the beam stiffness will always
increase the strength of the columns, unless, of course, the restraints yield. There
fore, it is essential that the design of beams in a frame that is free to sway reflects
the magnified moment developed at the column ends.
In the present study, a single bay fixed-base portal frame as shown in Fig.
4.1 was used as a frame model configuration. Some of the dimensions of the frame
model were inspired by an actual bridge design in Tucson, Arizona. However, the
following variables were selected for the purpose of the analysis:
• Shape of column cross section: circular and rectangular
• Column reinforcement ratio, p: 1, 3, and 5%
• Slenderness ratio, klu/r: 30, 50, and 70
where k is the effective-length factor for compression member, lu is the un
supported length of the column, and r is the radious of gyration.
• Axial load intensity, P/P0: 0.1, 0.3, 0.5, and 0.7
where P is the actual axial load applied, and PQ is the strength of the column
in pure compression.
• Ratio of flexural stiffness, EcIcoi/EcI{,eam: 0.23, and 1.18
where Ec is the modulus of elasticity of concrete, and Icoi and heam are the
moment of inertia of the gross cross sections of the column and beams, re
spectively.
• Distribution of total axial load: symmetrical and unsymmetrical loading.
In the symmetrical loading case, each column of the frame shown in Fig. 4.1
was loaded with an axial load, P, of 0.1Po, 0.3Po, 0.5P0, and 0.7P0. In the
unsymmetrical loading case only the right column was loaded with a total
axial load of P. In this case the values of P used were: 0.2P0 and 0.6Po.
Using the computer program FPIER, a parametric study was performed on
different combinations of variables that have been chosen. A total of 216 cases of
frames with a total of four different sets of beam and column cross sections were
analyzed. Ifeble 4.1 shows the dimensions of the beam and column cross sections
used. In this table, C-L indicates the set of beam and column cross sections used
in frames having circular column cross sections (C) and low flexural stiffness ratio
(L) of 0.23. The beam and column cross sections under the name C-H were used
in the frames having circular column cross sections (C) and high flexural stiffness
44
ratio (H) of 1.18. Similarly, R-L and R-H are the sets of beam and column cross
sections used in frames with rectangular column cross sections (R), and with low
and high flexural stiffness ratio of 0.23 and 1.18, respectively.
From the parametric study, the internal analytical moments at the four cor
ners of each frame were obtained. Then, comparisons were made between the pre
dicted analytical moments and the design moments predicted by the Moment Mag
nifier Method of the American Concrete Institute Code (ACI 318-83). To obtain
the predicted analytical moments, each member of each frame was divided into 10
segments of equal length, (see Fig. 4.2). A given set of vertical loads was applied
in one increment to the columns of the frame, followed by an incrementally lateral
load, H, applied to the west knee of the frame, until failure was reached.
In order to reduce the complexity of the analysis, the following parameters
were maintained constant:
• Shape of beam cross section: rectangular
• Doubly reinforced beam: p — 1% and p' = 1%
where p and p' are the percentage of steel reinforcement in the tension and
compression zone respectively.
• Bay span: 28 feet
• Concrete compressive strength, /c': 4000 psi
• Strength reduction factor for concrete: 0.85
• Modulus of elasticity of concrete, Ec: 3600 ksi

• Tensile yield strength of reinforcing steel, f y : 60000 psi
• Modulus of elasticity of steel, Es\ 29000 ksi
• Distance from extreme fiber of section to center of steel : 3 in
• No creep or sustained load effect was considered
Once the results from the computer program were obtained, the evaluation
of design moments, using the Moment Magnifier method, was carried out. This
was done based on an elastic analysis using gross cross section properties. The
magnifier factors 6b, and 8, in equation 2.1 (for braced and unbraced conditions)

The values of k were calculated using alignment charts based on the gross cross
section of the column, neglecting the steel reinforcement, and using half of the
flexural stiffness of the beam (0.5EcIg) also neglecting the steel reinforcement. The
stiffness parameter, EI, needed to calculate the elastic critical loads (Eqs. 2.3 and
2.6) was estimated by using EcIg/2.5 in the cases when p = 1% and EcIg/5 + EsIse
in the cases when p = 3% and 5%.
The results from the computer program, together with the prediction from
the ACI code for each frame were plotted in a common graph. Examples of these
plots are shown in Figs. 4.3, 4.4, and 4.5.
Each one of the 216 frames was named according to the following rules: The
first letter indicates the shape of the column cross section which can be rectangular
(R) or circular (C). The number following the first letter indicates the percentage
of steel reinforcement in the column. It can be 1, 3, or 5. The letter in the third
position means the ratio of flexural stiffness. It can be 0.23 represented by L (for low)

or 1.18 represented by H (for high). The following number indicates the slenderness
ratio: a number 3 is used for a nominal klu/r of 30, 5 for Klu/r of 50, and 7 for
klu/r of 70. The following letters (PP) indicate a symmetrical distribution of the
vertical load (one load P applied to each column simultaneously). In the cases of
unsymmetrical distribution, only one (P) is used, indicating that only the right
column is subjected to a load P. Finally, the last number indicates the intensity of
the axial load, P/P0, applied. It could be 0.1, 0.3, 0.5, and 0.7 for the symmetrical
loading cases or 0.2, and 0.6 for the unsymmetrical loading cases.
For example, the graph in Fig. 4.3, called R5L3PP0.3, corresponds to a frame
with rectangular column cross section having 5% of reinforcement. The frame has
low flexural stiffness ratio, 0.23, and a slenderness ratio of approximately 30. Two
symmetrical axial loads are applied to the columns of the frame, each one having
a magnitude of 0.3P„. This graph shows the variation of the moment in the four
corners of the frame (points a, b, c, and d), obtained from the computer analysis
and the design moment predicted by the ACI code as a function of the lateral
load, H. The variation of the analytical moments, with respect to the lateral load,
H, is almost linear in each corner of the frame, having the larger values at point
'a' and 'd\ The maximum moment predicted by the computer analysis was 87500
kip-in at point'd' while the ACI code method predicted a moment equal to 87300
kip-in which is in good agreement. This frame had a material failure at point'd'.
The graph in Fig. 4.4 belongs to the frame C5H3P0.2. This frame has circular
column cross sections with a reinforcement ratio of 5%. The frame has high flexural
stiffness ratio, 1.18, and a slenderness ratio of approximately 30. Only the right
column is axially loaded with a load P equal to 20 percent of the nominal axial
strength of the column. In this case there is more discrepancy between the moments
at the upper corners than with the moments at the bottom corners. A higher
moment of 32100 kip-in was obtained from the computer analysis at point'd'. The
ACI code underestimates the value of the moment predicting a moment equal to
27600 kip-in, about 14% less than the analytical prediction. This frame had a
material failure at point'd'.
Finally, Fig. 4.5 shows the results of the frame C3L5PP0.5. This frame
has circular column cross section with 3% of steel reinforcement. It has a flexural
stiffness ratio of 0.23 and a slenderness ratio of about 50. Both columns are axially
loaded, each one with a load P of 50 percent of the nominal axial strength of the
column. In this case, the ACI method overestimates the moment in the frame
by predicting a stiffer frame (greater slope). The prediction from the computer
analysis was 51300 kip-in at point 'a', while the ACI code predicted a moment
equal to 71900 kip-in, about 40% more than the analytical moment. This frame
also failed by material failure at point'd'.

CHAPTER 5
Analysis of Results
The results from the parametric study axe presented and analyzed in this
chapter. Each one of the 216 cases studied are represented by a ratio ACI/Analysis.
'ACI' represents the design moment predicted by the Moment Magnifier Method
of the American Concrete Institute Code (ACI 318-83), and 'Analysis' represents
the higher moment found at the four corners of the frame at failure, obtained from
the computer analysis which is considered the 'exact' solution. The ratio of these
two moments, ACI/Analysis, would then measure the accuracy of the ACI code
approach against the exact solution. A value of ACI/Analysis less than 1.0 would
indicate that the ACI code method underestimates the value of the moment in
the frame predicting a maximum moment for a given value of lateral load which
is smaller than the actual one; i.e. the ACI approach is unconservative. A value
greater than 1.0 would indicate that the ACI code method overestimates the actual
moment in the frame, i.e. the ACI approach is conservative. Finally, a value
of ACI/Analysis equal to the unity would, therefore, indicate excellent agreement
with the exact solution.
In the following sections, the accuracy of the ACI Moment Magnifier Method
is studied according to each one of the variables chosen in the parametric study:
axial load intensity, P/P0\ percentage of steel, p; slenderness ratio, fc/u/r; shape of
54
column cross section, and ratio of flexural stiffness. The analysis of the results for the
symmetrical and unsymmetrical vertical loading patterns axe presented separately.
A single asterisk (*), located in any of the tables presented in this chapter,
indicates that the solution of the computer program was neglected due to excessive
lateral deformation in the frame, or due to sudden stability failure when the vertical
loads were applied. A double asterisk (* *) indicates that the Moment Magnifier
Method predicts too large or negative sway magnifier factor, 6a, which means that
the frame is unstable.
5.1 Symmetrical Vertical Loading Pattern
5.1.1 Analysis according to the axial load intensity, P/P0:
Tables 5.1 through 5.4 shows the variations of the ratio ACI/Analysis with
respect to the level of axial load ( P/P0 ) for different percentages of steel ( p ). In
order to analyze the behavior of ACI/Analysis in relation to P/P0, it was necessary
to arrange them in different tables according to the other parameters. For instance,
Table 5.1 shows the ratio ACI/Analysis for frames having circular column cross
section, flexural stiffness ratio of 0.23, and slenderness ratio of 30, 50, and 70 (C-
L-30, C-L-50, and C-L-70, respectively). The ratio ACI/Analysis increases from
left to right at a given percentage of steel. For example, the frame C-L-30 with p
equal to 1% has ACI/Analysis ratios of 0.98, 1.06, 1.13, and 1.17 for levels of axial
loads ( P/P0) of 0.1, 0.3, 0.5, and 0.7 respectively. This denotes that the ACI code
method tends to be more conservative when the level of axial load increases. This
trend of variation was found in every case of Table 5.1.
Table 5.2 shows the ratio ACI/Analysis of the frames having circular column
55
cross section, a flexural stiffness ratio of 1.18, and slenderness ratio of 30, 50, and 70
(C-H-30, C-H-50, and C-H-70, respectively). A close look at this table would reveal
the increasing behavior of ACI/Analysis when the axial load increases. The ACI
code method predicts 2.96 times the value of the analytical moment for the frame
C-H-50 with />-equal to 1% and P/P0 equal to 0.7, and 2.49 times the analytical
moment for the frame C-H-50 with p equal to 3% and P/P0 equal to 0.7.
Table 5.3 contains the ratio ACI/Analysis of the frames having rectangular
column cross section, flexural stiffness ratio of 0.23, and slenderness ratio of 30,
50, and 70 (R-L-30, R-L-50, and R-L-70, respectively). This table shows the same
increasing variation of ACI/Analysis with an increase in the axial load applied. The
ACI method predicts more than two times the value of the actual moment in the
frame R-L-50 with p = 1% and P/P0 = 0.7. It also predicts twice the value of the
analytical moment in the case R-L-70 with p = 3% and P/P0 = 0.5.
Finally, Table 5.4 shows the ratio ACI/Analysis of the frames having rect
angular column cross section, flexural stiffness ratio of 1.18, and slenderness ratio
of 30, 50, and 70 (R-H-30, R-H-50, and R-H-70, respectively). Again, the same
trend was found. The ACI code method overestimates the moment in the frames
(becomes conservative) when the level of axial load increases.
5.1.2 Analysis according to the percentage of steel, pi
The Tables 5.1 through 5.4 are also used to analyze the behavior of the
ACI/Analysis with respect to the percentage of steel for the symmetrical vertical
loading pattern. Tbble 5.1 shows the variation of ACI/Analysis ratio in relation to
the percentage of steel for frames having characteristics C-L-30, C-L-50, and C-L-70.

At a given level of axial load, the ACI/Analysis ratio decreases when the percentage
of steel increases (from top to bottom) for most of the cases. For example, for frame
C-L-30 with P/P0 equal to 0.5 the values of ACI/Analysis are 1.13, 1.09, and 1.05
for percentage of steel of 1%, 3%, and 5%, respectively. However, this behavior was
not found when the columns are subjected to low axial load ( P/P0 = 0.1) where
the ratio ACI/Analysis tends to increase slightly when p increases.
In Table 5.2, the values of ACI/Analysis, for frames having circular column
cross section and flexural stiffness ratio of 1.18, are presented. The ACI code method
predicts less conservative values when the percentage of steel, p, increases. However,
in the cases C-H-70 with P/P0 = 0.1 and P/P0 = 0.3 there is a sudden increase of
ACI/Analysis at a p equal to 5%.
The values of ACI/Analysis for frames with rectangular column cross section
and flexural stiffness ratio of 0.23 are shown in Table 5.3. In these cases the ACI code
also predicts less conservative values for high values of percentage of steel except
for the cases of frames R-L-70 with P/P0 equal to 0.1 where the ACI/Analysis ratio
slightly increases when the percentage of steel increases.
The ACI/Analysis ratio for frames with rectangular column cross section
and flexural stiffness ratio of 1.18 are shown in Table 5.4. The ACI code approach
predicts less conservative values when p = 5%. The ACI code, however, is on the
unconservative side in the cases R-H-30 with P/P0 = 0.1 and p = 5%, and R-H-50
with P/P0 = 0.1 and p = 5% predicting, in both cases, moments which are 10%
lower than the actual moments.

5.1.3 Analysis according to the slenderness ratio, kl u / r :
The values of ACI/Analysis were rearranged in relation to the slenderness
ratio for a given percentage of steel in order to provide a better look at their be
havior. For example, Table 5.5 contains the ratios ACI/Analysis for frames having
circular column cross section, flexural stiffness ratio equal to 0.23, and levels of
axial loads P/P0 of 0.1, 0.3, 0.5, and 0.7 (C-L-PP0.1, C-L-PP0.3, C-L-PP0.5, and
C-L-PP0.7, respectively).
It can be seen that the ratio ACI/Analysis increases when the slenderness
ratio increases. For instance, in the case C-L-PP0.3 with p = 3%, the values of
ACI/Analysis are 1.05, 1.18, and 1.53 for slenderness ratios of 30, 50, and 70,
respectively, where the ACI code method predicts 53% more than the value of the
analytical moment when klu/r is equal to 70.
Table 5.6 shows the results from the frames having circular column crosss
sections, and flexural stiffness of 1.18 for each one of the level of axial load used. For
almost every case in this table, the ACI/Analysis ratio has an increasing variation
with an increase in the slenderness ratio, especially for higher level of axial loads.
In the same way, Tables 5.7 and 5.8 show the results from frames having
rectangular column cross sections, and flexural stiffness ratios of 0.23 and 1.18,
respectively. Once again, the same behavior was found. The ACI code method
becomes more conservative when the slenderness ratio increases, being more critical
for cases of frames with columns subjected to a high level of axial load.

5.1.4 Analysis according to the shape of column cross section:
In order to study the behavior of the ACI code predictions with the shape
of the column cross section, the values of ACI/Analysis ratio were rearranged in
different tables. Tables 5.9 through 5.14 show the ACI/Analysis ratio in relation
to the shape of the column cross section, where C indicates a circular cross section
and R indicates rectangular cross section. Frames with low flexural stiffness (L),
0.23, and slenderness ratio of 30, 50, and 70 are presented in Tables 5.9, 5.10, and
5.11, respectively. In the same manner, frames with high flexural stiffness (H), 1.18,
and slenderness ratio of 30, 50, and 70 are presented in Tables 5.12, 5.13, and 5.14,
respectively.
In most cases of frames in Tables 5.9, 5.10, and 5.11, the ACI/Analysis
ratios axe higher for frames with circular column cross section. However, the values
of ACI/Analysis for circular and rectangular column cross section are still very
close to each other. For example, the frame L-30-PP0.3 with p = 1% has a ratio
ACI/Analysis of 1.06 for circular cross section and 1.05 for rectangular column cross
section. The same behavior was found in the cases of frames shown in Tables 5.12,
5.13, and 5.14. In most cases, the ACI code method tends to predict slightly more
conservative values for frames having circular column cross section.
5.1.5 Analysis according to the flexural stiffness ratio:
Tables 5.15 through 5.20 show the ACI/Analysis ratio in relation to the two
values of flexural stiffness ratio used in the parametric study, 0.23 and 1.18. The
results of frames with circular column cross section and slenderness ratio of 30, 50,
and 70 are presented in Tables 5.15, 5.16, and 5.17, respectively, and those of frames

with rectangular column cross section, are presented in Tables 5.18, 5.19, and 5.20.
In the cases of frames shown in Tables 5.15 through 5.17, there was no specific
trend of variation of the ACI/Analysis ratio with respect to the flexural stiffness
ratio. In almost half of these cases the ACI code method predicted more conservative
values when 1.18 is used, and for the other half the ACI code predicted more
conservative values when the flexural stiffness ratio of 0.23 is used. In the cases of
frames with rectangular cross section (Tables 5.18 - 5.20), again no specific pattern
was found. However, in most cases, the ACI code predicted more conservative
values when the flexural stiffness ratio of 1.18 was used.
5.2 Unsymmetrical Vertical Loading Pattern
5.2.1 Analysis according to the axial load intensity, P/P0'
Tables 5.21, 5.22, 5.23, and 5.24 present the values of ACI/Analysis ratio
i n relation to the level of axial load (P/P0) and the percentage of steel (p) for
frames unsymmetrically loaded (only the right column was axially loaded). Table
5.21 shows the results of frames with circular column cross section, low flexural
stiffness ratio of 0.23, and slenderness ratio of 30, 50, and 70 (C-L-30, C-L-50, and
C-L-70, respectively). In this table, the ACI/Analysis ratios corresponding to an
axial load of 60% of the nominal column compressive strength (P/P0 = 0.6) are
higher than those corresponding to PJP0 = 0.2. The ACI code method, however,
underestimates the moment in some cases, such as in the case C-L-30 with p = 1%
and P/P0 = 0.2 where the prediction from the code method was 21% less than the
value of the analytical moment predicted. It also underestimates the moment in
the case C-L-30 with p = 1% and P/P0 = 0.6 where the prediction was 14% less

than the value of the actual moment. On the other hand, the ACI code method
overestimates the moments predicted in the cases C-L-50 with P/P0 = 0.6 where
the values predicted are 42%, 60%, and 49% greater than the values of the actual
moments corresponding to each one of these cases.
Table 5.22 shows the ACI/Analysis ratio corresponding to frames having
circular column cross section, flexural stiffness ratio of 1.18, and slenderness ratio of
30, 50, and 70 (C-H-30, C-H-50, and C-H-70, respectively). The Moment Magnifier
Method predicts more conservative values when P/P0 is equal to 0.6 especially
in cases C-H-50. However, the predictions were in the unconservative side in some
other cases. For example, cases C-H-30, with an axial load level (P/P0) of 0.2 where
the predictions, were 12% and 14% less than the analytical moment predictions for
p equal to 1 and 5%, respectively.
Table 5.23 shows the results of frames having rectangular column cross sec
tion, flexural stiffness ratio of 0.23, and slenderness ratio of 30, 50, and 70 (R-L-30,
R-L-50, and R-L-70, respectively). Again, the ratio ACI/Analysis is higher in the
cases with P/P0 of 0.6; however, the predictions from the ACI code were uncon
servative in some cases and conservative in other cases. The most imconservative
value was predicted in the case R-L-30 with p equal to 1% and P/P0 equal to 0.2
where the moment predicted was 24% less han the value of the analytical moment,
and the most conservative one was in the case R-L-70 with p = 3% and P/P0 = 0.6
where the ACI code predicted 3.87 times the value of the analytical moment.
Finally, Table 5.24 contains the results of frames having rectangular column
cross section, flexural stiffness ratio of 1.18, and slenderness ratio of 30, 50, and 70

is higher when the axial load applied is 60% of the nominal column compressive
capacity. The ACI code method predicts very conservative values in cases R-H-50
where the moments predicted are 68% , 103%, and 65% more than the analytical
moments predicted under an axial load level of 0.6 and reinforcement ratios of 1,
3, and 5%, respectively. In contrast, the ACI code method predicts unconservative
values in cases R-H-30 with P/P0 = 0.2 where the moments predicted were 18%,
12%, and 15% less than the actual moments for p equal to 1, 3, and 5% respectively.
5.2.2 Analysis according to the percentage of steel, pi
The ACI/Analysis ratio, in relation to the percentage of steel is also shown in
Tables 5.21, 5.22, 5.23, and 5.24. An examination of these tables would indicate that
there is no a specific trend of variation of the ACI/Analysis ratio with the percentage
of steel. In some cases, the ACI/Analysis ratio increases with an increase in the
percentage of steel, such as the cases C-H-70 with P/P0 = 0.2. In some other cases
the ratio ACI/Analysis decreases with an increase in p, such as the cases R-L-50
with P/P0 = 0.6 in Table 5.23. Also, in other cases there were no pattern because
the ACI/Analysis ratios are higher for p = 3% than for p = 1% and p = 5%, such as
the case C-L-50 in where the ACI/Analysis ratio is 1.42, 1.60, and 1.49 for p equal
to 1, 3, and 5% respectively under a level of axial load of 0.6.
5.2.3 Analysis according to the slenderness ratio, klu/r:
Tables 5.25, 5.26, 5.27, and 5.28 contain the ACI/Analysis ratio rearranged
in relation to the slenderness ratio. Table 5.25 shows the results of frames hav
ing circular column cross section, flexural stiffness ratio of 0.23, and level of axial
86
load of 0.2 and 0.6 (C-L-P0.2, and C-L-P0.6, respectively). As can be seen, the
ACI/Analysis ratio increases when the slenderness ratio increases. The ACI code
method underestimates the moment for the cases C-L-P0.2 with p = 1% and slen
derness ratio of 30 and 50 by 21% and 13%, respectively. It also underestimates
the results for the case C-L-P0.6 with p = 1% and slenderness ratio of 30 for about
14%. The Moment Magnifier Method tends to be more conservative in cases where
the slenderness ratio of 50 and 70 were used, especially in the cases with high level
of axial load (P/P0 = 0.6).
The results of frames having circular column cross sections, flexural stiffness
ratio of 1.18, and level of axial load of 0.2 and 0.6 (C-H-P0.2, and C-H-P0.6, re
spectively) are shown in Table 5.26. In these cases, the ACI/Analysis ratio also
increases with an increase in the slenderness ratio. The ACI code method tends to
be unconservative in the cases C-H-P0.2 with slenderness ratio of 30. In contrast,
the ACI predicts conservative values in cases C-H-P0.2 with slenderness ratio of 70
and C-H-P0.6 with slenderness ratio of 50.
Table 5.27 shows the ACI/Analysis ratios of frames having rectangular col
umn cross section, flexural stiffness ratio of 0.23, and axial load of 0.2Po and 0.6Po
(R-L-P0.2, and R-L-P0.6 respectively). The ACI/Analysis ratio has an increasing
variation when the slenderness ratio increases. The Moment Magnifier Method pre
dicts unconservative values in the cases of frames with slenderness ratio of 30 not
heavily loaded (P/P0 = 0.2) where the moments predicted are 12%, 7%, and 14%
less than the actual moments for p equal to 1, 3, and 5, respectively. The ACI code
method becomes more conservative for cases with high slenderness ratio of 50 and
70 and with heavy axial load.

In Table 5.28 the results of frames having rectangular column cross section,
flexural stiffness ratio of 1.18, and P/P0 of 0.2 and 0.6 (R-H-P0.2, and R-H-P0.6, re
spectively) are presented. These cases have similar behavior with the previous cases
(Table 5.27). The ACI code method is unconservative for cases with slenderness
ratio of 30 with P/P0 = 0.2, and it is conservative for cases where the slenderness
ratio is 50 and 70 respectively for high level of axial load (P/P0 = 0.6).
5.2.4 Analysis according to the shape of column cross section:
Tables 5.29 to 5.34 show the ACI/Analysis ratio in relation to the shape
of the column cross section for a given percentage of steel. Tables 5.29, 5.30, and
5.31 contain the information of frames having low flexural stiffness ratio of 0.23 and
slenderness ratio of 30, 50, and 70 respectively. A close inspection of these tables
would show that in most cases the ACI/Analysis ratio tends to be higher for the
cases where circular columns cross sections were used; however, the difference from
these values to those of the cases with rectangular column cross sections are small in
most cases. Table 5.32, 5.33, and 5.34 show the information obtained from frames
having a flexural stiffness ratio of 1.18. Again, in most cases the ACI/Analysis
ratios are higher for cases when circular column cross sections were used. However
these values are not too far from those of cases having rectangular column cross
section.
5.2.5 Analysis according to the flexural stiffness ratio:
Tables 5.35 through 5.40 show the ACI/Analysis ratio rearranged accord
ing to the two values of flexural stiffness ratios used in the analysis. The results
obtained from frames having circular column cross sections and a slenderness ra
tio of 30, 50, and 70 are presented in Tables 5.35, 5.36, and 5.37, respectively. In
the same way, the results obtained from frames having rectangular column cross
sections and slenderness ratios of 30, 50, and 70 are shown in Tables 5.38, 5.39,
and 5.40, respectively. A close look at these tables would show that in most cases
the ACI/Analysis ratio is higher in the cases where a stiffness ratio of 1.18 were
used. This indicates that the ACI code method predicts more conservative values
when the flexural stiffness increases, this behavior is more noticible for cases where
slenderness ratios of 50 and 70 were used.

CHAPTER 6
Summary and Conclusions
This thesis has been developed with the purpose of analyzing the accuracy of
the Moment Magnifier Method of the American Concrete Institute Code (ACI 318-
83) as an approximate design method of reinforced concrete frames. The analysis
was carried out by developing a parametric study based on different combinations of
six main variables that, according to some previous studies, have a great influence in
the behavior of reinforced concrete frames. These variables are: axial load intensity,
P/P0; column reinforcement ratio, p\ slenderness ratio, klu/r; shape of column
cross section, flexural stiffness ratio, and the axial load distribution. A total of
216 different cases of single bay fixed-base portal frames were examined, using the
computer program FPIER (Poston et al., 1983), to obtain the analytical 'exact'
solution. A given set of vertical loads were applied to the columns of each frame in
one increment followed by an incrementally lateral load, until failure was reached.
The higher analytical moment at the four corners of each frame at failure was then
compared with the design moment predicted by the Moment Magnifier Method of
the American Concrete Institute Code (ACI 318-83).
The comparisons showed that certain aspects of the observed responses were
different for the symmetrical and unsymmetrical axial loading cases. However, the
following conclusions hold true for both symmetrical (axial loads applied to both
106
columns) and unsymmetrical (axial load applied to one column only) loaded frames.
The Moment Magnifier Method predicts a conservative design moment for the frame
when:
• the axial load increases;
• the slenderness ratio increases; and
• when circular column cross sections are used.
For the frames loaded symmetrically, the Moment Magnifier Method pre
dicts more conservative moments when a low percentage of steel is used. It is also
concluded that the Moment Magnifier Method predictions did not show a specific
trend of variation according to the flexural stiffness ratio.
For the frames loaded unsymmetrically, the Moment Magnifier Method pre
dictions are conservative for low level of axial loads and low slenderness ratios. The
Moment Magnifier Method did not show a specific behavior according to the per
centage of steel used in the columns; however, the predictions are conservative when
high flexural stiffness ratio is used.

PROGRAM FPIER
The program FPIER was written by Dr. Randall W. Poston, Dr. Manuel
Diaz, Dr. Jose M. Roesset, and Dr. John E. Breen, with research support from the
Texas Department of highway and Public Transportation to the Ferguson Structural
Engineering Laboratory at the University of Texas at Austin. The primary objective
of the program is the structural analysis of a reinforced concrete frame up to two
bays and three stories with symmetrical configuration. The listing of the program
is presented in the following pages.
