STAAD Commands and
Input Instructions
Section
5
This section of the manual describes in detail various commands
and related instructions for STAAD. The user utilizes a command
language format to communicate instructions to the program. Each
of these commands either supplies some data to the program or
instructs it to perform some calculations using the data already
specified. The command language format and conventions are
described in Section 5.1. This is followed by a description of the
available commands.
Although the STAAD input can be created through the Modeling
mode, 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.
i) All design related data can be provided only after the analysis
command.
ii) All load cases and load combinations must be provided
together, except in a case where the CHANGE command is
used. 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.
