Title: The Effect of Warping Stress on the Lateral-Torsion Buckling of Cold-Formed Zed-Purlins
Abstract: An analytical model is developed for analysing the elastic lateral-torsion buckling of cold-formed zed-purlins with partially lateral restraint from metal sheeting. The model is used to estimate the effects of warping stresses on the lateral-torsion buckling behavior of cold-formed zed-purlins with various boundaries and interval braces provided by antisag bars. The results show that the warping stress only has remarkable influence on the lateral-torsion buckling when the boundary of the member is fixed and there is no antisag bar present.
