Abstract

This paper presents an analytical model for predicting the lateral-torsion buckling of thin-walled channel section beams partial-laterally restrained by metal sheeting when subjected to an uplift load. The critical load is determined by using energy methods. The focus of the study is to investigate the individual influences of moment variation along the longitudinal direction of the beam and of restraints provided by interval anti-sag bars and boundary conditions on the lateral-torsion buckling behaviour of the beams.
