Abstract
The use of stainless-steel results in significant life-cycling cost savings. It likewise has high-temperature properties, just as satisfactory weldability, and fracture toughness. This study investigates the behaviour ofstainless-steel plate girder under simultaneous bending and shear using commercial FE software Abaqus. For modelling stainless steel of grade Duplex EN 1.4462 (2205) was used, which possess twice the design strength of austenitic and ferritic stainless steels. Numerically validated models were used to conduct parametric study covering effect of flange slenderness and flange thickness to web thickness ratios. The results show a significant contribution of the flange on shear strength and bending moment capacity of stainless-steel plate girders. The contribution of the flange was also influenced by the presence of end rigid post and change in the panel aspect ratio.
