GTSELANCZOS Efficiency Improvements06.03.1410Dynamics (cont)The maximum allowable number of time points used for the acceleration time history integration procedure of the CREATE RESPONSE SPECTRUM command has been increased from 1 million to 4 million.

06.03.1411Dynamics (cont)The MODE FACTORS COMPUTE option of the RESPONSE SPECTRUM LOAD command has been updated to include the selection of the LINDLEY-YOW method for the computation of the rigid and periodic mode factors pursuant to the provisions of the U.S. Nuclear Regulatory Commission Regulatory Guide 1.92 Revision 2. The new command syntax is shown on the next slide:1206.03.14New12Dynamics (cont)Modified MODE FACTORS compute specs13

06.03.14New example13Dynamics (cont)A new option, BROADEN, has been added to the CREATE RESPONSE SPECTRUM command. When the BROADEN option is given, the created response spectrum points are also peak-broadened in a manner suggested by NRC Regulatory Guide 1.122 (Reference 69, Volume 3) and specified by ASCE 4-98, Section 3.4.2.3 (Reference 118, Volume 3), using a frequency variation factor that can be specified directly or taken as 0.15 by default. There is also an optional cutoff frequency parameter that allows a maximum frequency less than or equal to the maximum frequency of the unbroadened, intermediate response spectrum file to be imposed on the broadened response spectrum.

Documentation

Section 2.4.8.2, Volume 3.

1406.03.1414Dynamics (cont)A new command, CREATE RESPONSE SPECTRUM FILE command, has been implemented for Version 33. The CREATE RESPONSE SPECTRUM FILE command is used to envelope and broaden a set of input response spectrum files in a manner suggested by NRC Regulatory Guide 1.122 (Reference 69, Volume 3) and specified by ASCE 4-98, Section 3.4.2.3 (Reference 118, Volume 3). 1506.03.14New15Dynamics (cont)An example of the syntax of the CREATE RESPONSE SPECTRUM FILE command is shown below with an example of the results on the next slide:

06.03.14New example illustrating broadening17Dynamics (cont)Stiffness and mass matrix instabilities and/or ill-conditionality may cause convergence failure of the GTSELANCZOS/GT64MLANCZOS tridiagonalization Lanczos vector iterations, further causing the GTSELANCZOS/GT64MLANCZOS eigenvalue analysis to end silently, without providing any information about the failure of the analysis to produce results. This has been improved in Version 33, with the following message now being issued when this type of analysis failure is detected:

**** ERROR_GT64MLZEVA -- Problem detected in Lanczos vector iterations. The model may contain unremovable instabilities.Analysis terminated.1806.03.14New18External File SolversGTSESGT64MGTSELANCZOSGT64MLANCZOS1906.03.1419External File SolversThe external file solvers GTSES, GT64M, GTSELANCZOS and GT64MLANCZOS now use the folder GTSresults for all external files. GTSresults is created, if needed, in the current GTSTRUDL Working Directory. This results folder name is fixed and no user control is provided. This change will reduce the clutter in the Working Directory when the external file solvers are used.

New External File Folder

06.03.14Added screenshot of folder20External File Solvers (cont)Note: To be able to restore external file results saved (using the SAVE command) under version 32 or earlier and restored under version 33 (using the RESTORE command), before running GTSTRUDL 33 create a folder named GTSresults and copy all the external files to the new folder. 06.03.1421Finite Elements

2206.03.1422Finite ElementsThe CALCULATE AVERAGE command now has a SUMMARY ONLY option. If selected, only the summary for each active load is printed while results for individual joints are suppressed. If the ENVELOPE option is included, then the summary over all active loadings is printed.

Syntax:

CALCULATE AVERAGE type ((AND) ENVELOPE) ((SUMMARY) ONLY) -surface list

Where type, surface and list are defined in the Reference documentation

06.03.14New24General25InputOutput06.03.1425GeneralPrerelease features (Chapter 5 of the Release Guide) will now output a warning message indicating they are in prerelease status. This change allows Quality Assurance customers a simple way to be aware if they are using prerelease features. An example is shown on the next slide.

Command:

DESIGN SLAB USING WOOD AND ARMER - AVERAGE JOI 1 11 ELE 1Output

****WARNING_CRCCMN - This feature is a Prerelease feature. User feedback and suggestions are welcome.

06.03.1426General (cont)A new ALL option has been added to the list option of the PHYSICAL MEMBER COMPLIANCE CHECK command. This option allows users to check the compliance of all physical members in a single command. This feature is documented in the Section 2.1.2.10.2 of Volume 1.

06.03.1427General (cont)The CREATE AUTOMATIC command has two new features: First is the option to create FORM LOADS, which are independent loads suitable for nonlinear analysis. Second is the option to use multiple SETS of EXCLUSIVE loads, which allow you to create loadings by combining one load (or load group) from each SET. For example, this gives you the ability to create all combinations of Live and Wind loads by putting the different load types in different SETs.

06.03.1428General (cont)New syntax for the CREATE AUTOMATIC command:

06.03.1429General (cont)Example of the revised CREATE AUTOMATIC command with multiple EXCLUSIVE commands in different SETS:

CREATE AUTOMATIC LOAD COMBINATIONS INITIAL 101 CONSTANT DL 1.4EXCLUSIVE LL1' LL2' LL3' LL4' 1.6$ Assumed SET 1 EXCLUSIVE SET 2 WL1' WL2' 1.7 $ Specified SET 2 END The above commands will create 8 load combinations as shown on the next slide.06.03.1430General (cont)

06.03.1431General (cont)The AREA LOAD command has been enhanced with two new features for ELEVATION. The EXCEPT option will now accept multiple regions, allowing the specification of all the holes (stairwells, atria, etc.) in a floor in a single ELEVATION command. 06.03.1432General (cont)A new option IGNORE MEMBERS has been added to allow the specification of members to not include in the AREA LOAD calculations. Previously these unloaded members, such as braces, needed to be INACTIVE before issuing the AREA LOAD command.Examples are shown on the next slides.

06.03.1433General (cont)ELEVATION 36.75 EXCEPT LIMITS JOINTS 345 789 LIMITS MEMBERS - 45 78 124 158 VALUE TWO WAY 100.0

Two holes are not loaded, the first bounded by joints 345 and 789 and the second outlined by members 45, 78, 124 and 158.

ELEVATION 36.75 IGNORE MEMBERS B1' TO B12' VALUE TWO WAY 100.0

The areas and loadings are determined without considering bracing members B1' to B12'. These members will not be loaded and their ACTIVE/INACTIVE status is not affected.

06.03.1434General (cont)RESTORE will now internally re-issue a LARGE PROBLEM SIZE n command if such a command had been given when the SAVE command was executed. This only applies to Version 33 and later. .gts files created under earlier versions can be restored but no automatic LARGE PROBLEM SIZE command will be generated.

If the LARGE PROBLEM SIZE command is generated, an INFO message is printed:

****INFO_XXREST - LARGE PROBLEM SIZE 5 restored.

06.03.1435General (cont)Three new features have been added to the SELF WEIGHT LOADING RECOMPUTE command (Section 2.1.11.3.1.2, Volume 1). The first two options can be used to recompute active and inactive (default) or active only self weight loads. The third option allows the user to reform active form loads also.

Documentation:Section 2.1.11.3.1.2, Volume 1.

3606.03.14New36General (cont)The CALCULATE PRESSURE command now only evaluates elements or element faces that lie in the specified plane, e.g. PLANE Y EQUAL 0.0 if no element list is given. Previously, all elements in the model were evaluated and the command would fail if elements existed that were not in the specified plane.

Example:

CALCULATE PRESSURE PLANE Y 0.0 SUMMARY ONLY

Will now report pressures based on only those elements or element faces that lie in the plane Y = 0.0.

Documentation:

Section 2.1.12.19 The CALCULATE PRESSURE Command

3706.03.14New37General (cont)Active solver status information has been added to the data base summary report produced by the QUERY and RESTORE commands.

Documentation:

QUERY Command, Section 2.1.12.2, Volume 1The SAVE/RESTORE Commands, Section 2.1.2.4.2, Volume 13806.03.14New38General (cont )The CALCULATE SOIL SPRING VALUES command now has a PRINT OFF option to suppress individual joint output. This prevents large amounts of output when the specified plane contains many joints. When the COMPRESSION ONLY option is not used, a summary of how many joints and tributary elements were involved is the only output.

3906.03.14New39General (cont)STIFFNESS ANALYSIS will now print a warning message if any statics checks failures are found. This new message will trigger the Warning Message facility in the GTSTRUDL Output Window (Section 2.6) to alert you to the existence of statics check failures in case they are not visible in the window due to statics check failure output such as shown below:

Example:

STIFFNESS ANALYSISSTATICS CHECK FAILED FOR JOINT 5 FOR LOADING CONDITION 6 AT DOF DX APPLIED LOAD= 0.00000E+00 CALCULATED LOAD= 0.50000E+04 COMPARISON VALUE= 0.13277E+02

New UNDO button06.03.14UNDO function added as requested by GTSUG 52GTMenu (cont)Redraw Solid now uses the element color for the cable element, IPCABLE, and the transmission line element, IPTL. Previously, the color for curves and lines was used for the cable and transmission line elements when using Redraw Solid. Display Model will now display the cross section for members that have properties created using the Member Property Channel and Polygon cross-section specs. The Polygon cross sections will be drawn as pipes.

06.03.14GTMenu (cont)The time to enter GTMenu with a model which contains a large number of joints loads has been greatly reduced.The time to display wire frame models which contain a large number of finite elements has been greatly reduced.The time for Redraw Solid has been greatly reduced for large models.The time to Exit GTMenu and save the changes has been reduced for models which contain a large number of solid elements.Display Parameters will now display the parameters UNLCFTF and UNLCFBF.The STOP box will now always appear in the Graphics Window when animating mode shapes or deformed shapes.

06.03.14The first item was found by Aristidis customer joint loads at every dof due to missing mass calc. Time went from 20 minutes or higher down to much less than a minute.54GTMenu (cont)As a result of the improvements to the wire frame display of models which contain a large number of finite elements, the time for Print Preview in the Scope Editor has been significantly decreased due to the reduced number of lines which are now being drawn. An example of the Scope Editor before and after these changes is shown on the next two slides.06.03.14

06.03.14OffshoreThe SAVE command now saves the data computed by the COMPUTE FATIGUE LJF command. This enhancement enables the COMPUTE FATIGUE LJF command and a subsequent PERFORM FATIGUE ANALYSIS command to be executed in consecutive jobs separated by SAVE and RESTORE commands, the first job executing the COMPUTE FATIGUE LJF command and ending with a SAVE command and the second job beginning with a RESTORE command and executing the PERFORM FATIGUE ANALYSIS command.06.03.14Offshore (cont)A new option has been added to the PRINT FATIGUE command as follows:PRINT FATIGUE NUMBER OF WAVES

The PRINT FATIGUE NUMBER OF WAVES command prints a tabular report of the number of waves of the various distinct wave height-period pairs in each of the specified wave directions.

The format of the new report is shown on the next slide.06.03.14

06.03.14Offshore (cont)A new DAMAGE option has been added to the LIST FATIGUE command as follows:

06.03.14Offshore (cont)This command produces a report of the fatigue damage in a table ordered on wave height/period and direction. The report is produced for the critical point (point with the highest damage) at the end of each brace connected to each specified joint. This report also includes the center of damage with respect to wave height/period for each direction. An example of the format of the new report is shown on the next slide.06.03.14

06.03.14Offshore (cont*)The following fatigue analysis commands have been enhanced to support the use of the GTSES solver when activated by the ACTIVE SOLVER GTSES/GT64M command:

ASSEMBLE FOR FATIGUESOLVE FOR FATIGUECOMPUTE FATIGUE LJFPERFORM FATIGUE ANALYSIS06.03.14Offshore (cont)A new GTSELOS feature has been implemented whereby additional tables express the drag parameters CD and CM as function(s) of one or more of the existing pipe member diameter, water depth, Reynolds number parameters, plus the additional parameters roughness and Keulegan-Carpenters Number.

06.03.14Steel Design

7506.03.14Steel DesignThe AISC 14th Edition design code has been implemented. Both LRFD (load and resistance factor design) and the ASD (allowable strength design) methods of the AISC Fourteenth Edition are implemented. 06.03.14Steel Design (cont)This new code, AISC14, may be used to select or check any of the following shapes:Design for bi-axial bending and axial forces: I shapesChannelSingle AnglesTeesDouble AnglesSolid Round BarsSolid Rectangular and Square Bars Design for bi-axial bending, axial and torsional forces:Round HSS (Pipes)Rectangular and Square HSS (Structural Tubes)

06.03.14Steel Design (cont)New and modified Parameters for the AISC14 code:CODE AISC14 ALLIf using METHOD ASD, the following parameter may be used to specify an ASD reduction factor for the second order analysis results which should be analyzed for 1.6 times the ASD loadings: ASDRF 1.6 ALL

Other parameters that are specific to AISC14:CombEqs parameter to indicate which flexure and axial force combined equation from Section H1 or H2 is to be used.SECNDARY parameter is applicable to the stiffened element of I shapes which are used as diagonal braces

06.03.1478Steel Design (cont)The ANSI/AISC N690-12, specification for safety-related steel structures for nuclear facilities has been added. This code is based on the AISC steel construction manual, Fourteenth Edition specification with a few modifications. Both LRFD (load and resistance factor design) and the ASD (allowable strength design) methods of the AISC Fourteenth Edition are applicable.

Applicable cross-sections for N690-12 are I shapes, Channel, Single Angles, Tees, Double Angles, Round HSS (Pipes), Rectangular and Square HSS (Structural Tubes), Solid Round Bars, Solid Rectangular and Square Bars.

06.03.14Steel Design (cont)New parameters for N690-12:StemTees parameter for the unstiffened element of the stem of tee shaped compression members.ColSMF parameter to limit the width to thickness ratio of flanges of built-up box sections of columns in SMF systems.06.03.14Steel Design (cont)The transmission tower provisions, slenderness ratio and computation of the number of bolts, are now implemented in AISC14 code. When a value of YES has been specified for parameter TowerCK, transmission tower provisions are checked in addition to the provisions of the AISC14 code. Applicable cross-sections are single and double angles.

06.03.14Steel Design (cont)Elastic shear resistance of the EC3-2005 has been modified to use the first moment of area. The local shear stress, ED, in the Equation 6.20 of the EN 1993-1-1:2005(E) is now computed using the first moment of area (e.g. S). The thickness, t, in the Equation 6.20 also has been modified to use the total thickness of the cross-section to resist the shear force.

A new steel grade, A1011G33, has been added to the AISI89 code for the UNISTRUT cross-sections. This is the ASTM steel grade A1011 with a yield stress of 33 ksi.

06.03.14Steel TablesNew Imperial and Metric tables from the AISC 14th edition have been added.The tables for rectangular and circular concrete sections have been moved to a release status. The table names are CONCIR and CONRECT.

The modified Loading page is shown on the next slide.06.03.14Base Plate Wizard (cont)

New ability to change unitsNew Edit and Delete buttons06.03.14Base Plate Wizard (cont)A new Run Analysis option has been added to the File menu. After loadings have been added to the Base Plate or a .gtbp file with loadings and either anchors or constraints has been read, this menu selection will automatically create an input file including analysis and process the file. If File - Write GTSTRUDL input has been used, those dialog settings (file name, result types, .gts file) are retained and used by Run Analysis.

The revised File menu is shown on the next slide.

06.03.14Base Plate Wizard (cont)

06.03.14Base Plate Wizard (cont)Two new pipe and hollow shape tables have been added to the GTStrudl\33\BasePlate folder:PIPES9.txt and RdHSS13.txt.

These tables correspond to the GTSTRUDL standard tables of the same name. The profiles can be accessed by using the Options - Attachment file menu pick or by concatenating one or both files to your current default attachment file. 06.03.14Base Plate Wizard (cont)A new results type has been added: Constraint Reactions.Constraint Reactions are only applicable to constraints with restrained boundary conditions. Constraint Reactions are available through the Results - Constraint reactions menu pick, or as part of the Results Summary. 06.03.14Base Plate Wizard (cont)Constraint Reactions consist of the force reactions FX, FY and FZ for each joint in the constraint, plus the SRSS (Square Root Sum of the Squares) of the three shear values. You can request the reaction moments MX, MY and MZ if desired. Constraint Reactions are equivalent to the GTSTRUDL command :

LIST REACTIONS JOINTS GROUP CON1' (for constraint #1).06.03.14Base Plate Wizard (cont)A new results type has been added: Attachment Displacement.Attachment Displacement is the displacement of the control or load point of an attachment due to the applied loads. It is equivalent to the GTSTRUDL command:

10606.03.14Dynamic AnalysisImplement GTSES/GT64M versions of linear direct integration (physical) transient analysis.

Computation of minimum seismic load according to latest IBC provisions.06.03.14Dynamic Analysis (cont)Response spectrum analysis will keep a record of eigenvalue analysis results on a load-by-load basis. This will be particularly useful when the results of different eigenvalue analyses are used for different response spectrum load analyses in the same job, and mode combinations such as CQC, which is a function of damping ratio and frequency, are used.

The LIST DYNAMIC PARTICIPATION FACTORS command will be enhanced to also list the frequencies of each mode.

Improve the efficiency of the GT64MLANCZOS eigenvalue solver for very large jobs that require very high numbers of modes (e.g. 300,000 DOFs and 10,000 modes).

06.03.14Finite Elements

10906.03.14Finite ElementsImplement local element coordinate system results processing (text reports and graphical display of stress contours) for selected planar elements, in particular the SBHQ and SBHT family of plate elements and the SBMITC element. This is particularly convenient and useful for structures formed by surfaces of revolution.

Implement CALCULATE ELEMENT (result) command to calculate and output stresses for each element (no averaging) at top, middle and bottom surfaces. The results for this will also be used by GTMenu to contour each elements results.*06.03.14Calculate Element is new110Finite Elements (cont)Implement new 3 node plane stress, plate bending and plate triangular elements. The plane stress element will have 3 DOF (two translational DOF and a drilling DOF). The plate bending element will model moderately thick plates.

06.03.14Offshore

12706.03.14OffshoreImplement procedures that enable GTSTRUDL to perform the required dynamic analyses of GTSELOS wave load data and to use the dynamic wave force results in fatigue analyses.06.03.14Offshore (cont)GT STRUDL fatigue analysis is presently restricted to the use of a single S-N curve that applies to all members undergoing a given fatigue analysis. An improvement to this procedure is planned whereby multiple S-N curves can be defined as functions of pipe member wall thickness, a reference thickness, a thickness exponent, and a stress range and assigned individually to members for the fatigue analysis.06.03.14Offshore (cont)An Influence Matrix approach to perform hotspot fatigue analysis of connection details other than simple tubular joints is planned.
