✦ Synopsis

This paper presents an analytical model for predicting the lateral-torsion buckling of thinwalled 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.

Flexural strength limits of steel single-angle section beams should be calculated based on the full plastic moment capacities, local buckling resistance and lateral torsional buckling capacities of the angle sections. The angle section beams are generally under the effect of external loads applied a
