Buckling of Axially Loaded Members (Columns)

Abstract

The classical critical load theory of perfect axial members assumes that the member in question is initially straight, slender, of solid cross section with flexural stiffness rigidity EI being constant throughout its length and subjected to an axial compressive force applied along the centroidal axis of the member. Moreover, it is presumed that the material of the member is homogeneous, isotropic and perfectly elastic. The assumption of small deflection theory of bending also holds good for the critical load theory.
