WebInstructions. The Column Buckling calculator allows for buckling analysis of long and intermediate-length columns loaded in compression. The loading can be either central or eccentric. See the instructions within the documentation for more details on performing this analysis. See the reference section for details on the equations used. Webresistance of the member (its buckling load) is limited by these flexural effects. The various modes of buckling are described below. Expressions for evaluating elastic critical buckling loads are discussed in Section 3 and the determination of buckling load according to member slenderness and material strength are discussed in Section 4.
