Thin-Walled Beam Formulations with Cross-Sectional Deformation
Thin-walled beams are widely used in steel construction with various restraint arrangements and sizes. Due to the slenderness of their cross-section thin-walled beams are prone to distortional behaviour as a result of web bending. Web bending is a major concern in thin-walled buckling behaviour especially when the top flanges are restraint as in highway bridge construction of girders. Web distortion also gains significance with slender webs, stocky flanges, and/or shorter spans. This paper evaluates the performance of beam-type Finite Element formulations that are capable of capturing the deformation modes involving web distortion in thin-walled beam behaviour by contrasting the analysis results against shell element-based models. In the selected case studies elastic buckling load predictions and corresponding first mode shapes of steel girders with various sizes and restraining conditions is illustrated.
