Local Buckling of Cold-Formed Steel Members with Edge Stiffened Holes

Marsel Garifullin, Darya Trubina, Nikolai Vatin

Abstract

Cold formed steel members with edge stiffened holes are a new generation of cold formed members recently developed by the building industry. Very little research has been performed on such sections to determine their local and distortional buckling capacity. This article provides the numerical results of elastic local buckling analysis of cold-formed lipped channels with edge stiffened holes. For flexural elements values of critical buckling moments are calculated and the influence of hole spacing and diameter on elastic buckling capacity is determined.
