Abstract

Channel steel columns utilized for industrialized steel houses have a buckling mode including bending and twisting. Their strength of flexural torsional buckling is lower than their strength of flexural buckling. However, their strength of flexural torsional buckling can be improved by stiffening members relatively easily, because they buckle in elastic range and their plate thickness is thin. This paper describes improvement on their strength of flexural torsional buckling and detail of their buckling mode by means of energy method.
