T.1 Re-specifying the analysis command

When the analysis and design engine executes the member selection operation you specified in the previous step, a new set of properties will end up being assigned to those members. This changes the stiffness distribution for the entire structure. Since the structure is statically indeterminate, it should be analyzed again to determine the correct the nodal displacements, member forces, etc. to reflect this new stiffness distribution.

The STAAD input file commands generated are:

PERFORM ANALYSIS

Select the Select command in the Analysis - Whole Structure dialog outline of the model commands.
On the Analysis and Design ribbon tab, select the Analysis Commands tool in the Analysis Data group.

The Analysis/Print Commands dialog opens.

Tip: If the Analysis/Print Commands dialog does not open automatically, then click Define Commands in the Analysis - Whole Structure dialog.
Select the Perform Analysis tab.
Select the No Print option.
Tip: The statics check report does need to be repeated.
Check the After Current option. This allows you to specify that where the new command is added. This will place the new Perform Analysis after the command selected in Step 1, instead of in the first valid point within the model file.
Click Add.
Click Close.
