What is FEMAP Buckling Analysis Tutorial about?

This document describes solving for the buckling modes of a bi-supported beam under compression using finite element analysis. A 10m long beam with rectangular cross-section is modeled with 10 CBAR elements. Boundary conditions of an articulated support on one end and roller on the other are applied. Linear buckling analysis calculates the first 5 buckling modes, with the lowest being 467.2N in the XZ plane as predicted by theory. The 5th mode of 11,681N occurs in the XY plane as expected for this proble
