Elastic Buckling of Single-Stepped Columns with End and Intermediate Axial Loads

Buckling study of single-stepped columns subjected to both intermediate and end axial loads are introduced in this paper. The column understudy is considered as two segments where the upper and the lower parts have different cross section moment of inertia or different material and subjected to inte...

The column understudy is considered as two segments where the upper and the lower parts have different cross section moment of inertia or different material and subjected to intermediate load at the location of the cross section change beside the end load. All the classical end conditions of the studied column are considered in this paper as pinned ends, clamped ends, clamped-free ends and clamped-pinned ends.

These parameters are i) ratio of the intermediate axial load to the end axial load, ii) the intermediate load location as a ratio to the column span and, iii) the ratio of flexural rigidity of lower segment to that of upper one.
