TR.0 STAAD Commands and Input Instructions
Although the STAAD.Pro input can be created through the Analytical Modeling workflow, it is important to understand the command language. With the knowledge of this language, it is easy to understand the problem and add or comment data as necessary. The general sequence in which the commands should appear in an input file should ideally follow the same sequence in which they are presented in this section. The commands are executed in the sequence entered. Obviously then the data needed for proper execution of a command must precede the command (e.g., Print results after Perform Analysis). Otherwise, the commands can be provided in any order with the following exceptions.
- All design related data can be provided only after the analysis command.
- All load cases and load combinations must be provided together, except in a case where the
CHANGE
command is used (see TR.38 Change Specification). Additional load cases can be provided in the latter part of input.
All input data provided is stored by the program. Data can be added, deleted or modified within an existing data file.
In-Core Versus Out-of-Core
- Number of nodes >30,000
- Number of nodes times the number of active primary load cases > 1,600,000
Though selection of the mode is automatically chosen by the analysis, it can be overridden using the SET STAR
command:
-
SET STAR 3
– default -
SET STAR 4
– use out-of-core solver regardless of size
