GT STRUDL Summary of DBX Commands

V 5 Summary 1 - 1 Rev T

Summary of GTSTRUDL DBX Commands

The structure and syntax of the DBX FILE SPEC command and the DBX WRITE

command are summarized below.

1. DBX FILE SPEC Command

Individual Format:

DBX ( FILE ) ( SPECS ) -

Tabular Format:

DBX ( FILE ) ( SPECS ) -


14/167

Summary of DBX Commands GT STRUDL

Rev T Summary 1 - 2 V 5

where:

Data Elements:

'filename' = character string which defines the name of a DBX file. 'file-

name' cannot exceed 80 characters.

'description' = character string which defines the description of the

DBX file. 'description' cannot exceed 60 characters.

Purpose:

The purpose of the DBX FILE SPEC command is to specify the file name,

format, and access mode characteristics of a DBX file for subsequent use in a

DBX WRITE command.


15/167



2. The WRITE Command

General form:

where,

REPLACE

= indicates that if a file with the specified name already exists, it will

be over-written with this data file. EXISTING and FILE are op-

tional words and have no effect.

UNREGISTERED

= indicates that the created DBX file information will not be entered

into the DBX directory information. In addition, a FILE SPECS

command does not need to precede a WRITE UNREGISTERED

command. UNREGISTERED files are always written in ASCII80

format, in REPLACE mode.

'filename'

= Name of the DBX data file, limited to 80 characters. If 'filename' is

omitted, the default file name is used. The default file name will be

composed of the letters 'STDBX' and the data class index of theDBX data. For example, the directory data class index is 1 and the

default file name is 'STDBX01'.

JOINT RESULTS are data class 10, described in Table 1-9. The JOINT RE-

SULTS file contains the joint ID, the load ID, results flag, displacements and

rotations, and computed joint forces and moments (reactions). The SUPPORTS

ONLY option will filter the specified joint list to only include joints that have

been designated as supports, facilitating the export of data for foundation design.

MEMBER RESULTS are data class 11, described in Table 1-10. The MEMBER

RESULTS file contains the member ID, the load ID, results flag, local forces and

moments at member start and end, and differential displacement and rotation

between the start and end of the member.

SECTION FORCES are data class 12, described in Table 1-11. The SECTION

FORCES file contains the member ID, the load ID, the section number, results

flag, distance from the member start to the section, and local forces and moments

at the section. The NS option will override any previous SECTION specification

for the member and will report NS sections evenly spaced from the start to the

end of the member. If no SECTION specification for the member has been given

and the NS option is not specified, NS will default to 11 sections.

SECTION DISPLACEMENTS are data class 9, described in Table 1-28. The

SECTION DISPLACEMENTS file contains member ID's, load ID's, section

number, results flag, distance from the member start to the section location, and

displacements (X, Y, Z) at the section. Displacements are reported in the member

reference frame, unless GLOBAL is specified, then displacements are reported inthe global reference frame. The NS option will override any previous SECTION

specification for the member and will report NS sections evenly spaced from the

start to the end of the member. If no SECTION specification for the member has

been given and the NS option is not specified, NS will default to 11 sections.

AVERAGE FE (ELEMENT STRESSES, ELEMENT STRAINS, ELEMENT

PRINCIPAL STRESSES, ELEMENT PRINCIPAL STRAINS, PRINCIPAL

RESULTANTS, PRINCIPAL MEMBRANE RESULTANTS, PRINCIPAL

BENDING RESULTANTS, and VON MISES) results have data classes 33 to 40,

described in Table 1-12. The AVERAGE FE results files contain the joint ID, the

load ID, surface index, number of elements used in the average, and the average

results. Tables 1-12a through 1-12e describe the results; Figures 1-2 through 1-7

have diagrams for results interpretation. Note that 'elist' should be a list of joints.

SUPERELEMENT DEFINITION file contains the number and ID's of all bound-

ary nodes and internal elements for each superelement requested.

SUPERELEMENT STIFFNESS is data class 29, described in Table 1-25. The

SUPERELEMENT STIFFNESS file contains the condensed superelementstiffness array arranged in sub-matrix form, with a header record and data record

for each sub-matrix.

SUPERELEMENT LOAD is data class 30, described in Table 1-26. The

SUPERELEMENT LOAD contains the condensed load vectors for each active

loading for all boundary nodes. Active DOF are indicated for each boundary

node.

DESIGN STANDARD file contains the member ID, design type, design code, bar

table, cross-section dimensions, and reinforcing bar information.
