To instruct the program to perform a buckling
analysis on the structure, use the following procedure.
This analysis type
is used to calculate the buckling factor for a load case. This is the load case
multiplier at which global buckling of the structure would occur for that load
case.
-
Either:
-
select the
Analysis page
- on
the
Analysis and Design ribbon tab, select the
Analysis Commands tool in the
Analysis Data group
The
Analysis/Print Commands dialog
opens.
-
Select the
Perform Buckling Analysis tab.
-
Select the method for the buckling analysis:
- Iterative method
- Eigen method - available for STAAD.Pro Advanced
only
- Optional:
If the iterative method is used, type the maximum Number of
Iterations to use in the analysis.
It not specified (i.e., left as zero), 20 iterations are used as the
default value. 15 is recommended.
Note:
MAXSTEPS
input is ignored
when using the eigen method.
-
Select the
Print Option you want to use.
-
Click
Add.
The perform buckling analysis command is added to the input
file.
