This paper presents a study of the behaviour of Lateral-Torsional Buckling (LTB) that is one of the common failure modes of large span beams. LTB for non-prismatic I-beams still needs more investigations, due to its sophisticated formulation for cross-section properties. This paper presents the results of numerical (Finite Element Software ABAQUS) and theoretical analysis for LTB of a simply supported I-beam with triangularly tapered corrugated web under concentrated loads. The corrugation densities adopted in this study represent the most commonly used types for such structures in practice of construction. For numerical analysis, the formulas were adopted from the case of a trapezoidal corrugated web, which is successfully verified by different authors. Recommendations of this study are given for simply supported tapered triangularly corrugated web at lateral torsional buckling.
