How can I restrict STAAD.Pro to carry out buckling analysis for certain load cases only ?
By default, the program calculates buckling factor for all primary/REPEAT LOAD cases but you can insert a PERFORM ANALYSIS & CHANGE after the cases for which you do not need to carry out buckling analysis. After the CHANGE, specify the loads for which BUCKLING ANALYSIS us required. A sample piece of code is provided below.
LOAD 1
ELEMENT LOAD
41 TO 72 PR -1
LOAD 2
JOINT LOAD
11 33 FZ -20
22 FZ -100
...
LOAD 12
REPEAT LOAD
1 1.2 2 1.2
PERFORM ANALYSIS
CHANGE
LOAD 13
REPEAT LOAD
1 1.0 2 1.0
LOAD 14
REPEAT LOAD
1 1.2 2 1.4
PERFORM BUCKLING ANALYSIS
CHANGE
...
In the above example the BUCKLING ANALYSIS would only be carried out for cases 13 and 14 and will not be carried out for cases 1 to 12.
