WebColumn Buckling Calculation and Equation - When a column buckles, it maintains its deflected shape after the application of the critical load. In most applications, the critical load is usually regarded as the maximum load sustainable by the column. Theoretically, any buckling mode is possible, but the column will ordinarily deflect into the first mode.
