To specify a buckling analysis
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.
- Add or edit an existing analysis set in the Analysis Commands dialog .
- Select Buckling from the Analysis type drop-down list. This instructs the analysis engine to perform a second order, P-Delta analysis.
- Select the desired Print option for including analysis results in the output file.
-
Select the method of the buckling analysis:
- Iterative
- Eigen
- (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.
- Click OK.
