Wagners Beam Cycle (No. R916)

Abstract

This paper summarises a number of research studies on the torsion and buckling behaviour of beams which derive from a theory developed by Wagner, who extended Timoshenko’s treatment of the elastic buckling of I-section beams and columns to members of general thin-walled open cross-section. These studies include applications of the first-order Wagner theory to the buckling of beams and cantilevers, and of the second-order Wagner theory to the large rotations and post-buckling behaviour of beams.
