Abstract: This paper presents the experimental testing and numerical simulations of four full-scale I-shaped welded steel girders to examine their lateral–torsional buckling (LTB) and lateral–distortional buckling (LDB) behaviors ...

Abstract: Recent studies investigating lateral torsional buckling suggest that North American steel design provisions may overestimate the bending resistance of welded girders that buckle laterally in the inelastic range. Furthermore, ...
