Buckling analysis

A buckling analysis is required where it is important to investigate the potential effects of buckling on the structure. These effects can be significant well before a structure actually buckles.

There are two approaches to buckling – eigenvalue buckling and nonlinear buckling. The follow section reffers to eigenvalue buckling analysis, which looks at buckling load factors and the corresponding buckling mode shapes, for a structure with a particular load.

In this section you will find entries on:

For information how to perform a nonlinear buckling analysis, please refer to this reference entry on using nonlinear static analysis to evaluate buckling. Note that nonlinear buckling analysis differs from eigenvalue buckling analysis in that it looks at the response of the structure to a particular load as the load is increased and the effects of buckling begin to show. Nonlinear buckling cannot, in general, reveal higher modes.
