There is no commonly accepted and reliable design method to determine the lateral–torsional buckling (LTB) resistance of steel trapezoidally corrugated web girders. Therefore, focus current paper on investigation this failure mode, detailed evaluation structural behavior determination accurate LTB resistance. An advanced finite element (FE) model developed validated using results laboratory tes...

The mechanical behaviour and design of fixed-ended steel equal-leg angle section members subjected to axial compression are addressed in this study. First, the critical buckling is described. Experimental data on columns collected from literature then used for validation numerical (shell finite element) models, developed within commercial package ABAQUS. Validation performed by means comparison...
