Abstract

Elastic local buckling strength of square hollow section members under biaxial bending shear force and axial force is theoretically presented by considering coupled effects of plate elements. Simple approximate formulas for calculating the coupled local buckling strength corresponding to boundary conditions at both ends, shape and stress distribution with respect to the members are presented. By application of these formulas, it is shown that square hollow section members with large width-thickness ratio can be used from the viewpoint of buckling strength by considering coupled effects of plate elements and stress distribution in members.
