Column buckling theory
WebEuler Buckling Theory is the classical theory presented in textbooks and classrooms. It begins simply by noting that the internal bending moment in a loaded and deformed column is −P y − P y where P P is the … Webwhere L eff is the effective length and L is the actual unsupported length of the column. For example, the theoretical effective length of a fixed-free column is 2L.The fixed-free column is twice as susceptible to buckling …
