000011148 520__ $$2eng$$aIn the last three decades, many researches have been carried out on steel plate shear walls, SPSWs, and they have been introduced as seismic load resisting systems. However, their non-linear behaviour complexities such as buckling, post buckling and tension field action of infill steel plate, in-elastic out-of-plane large deformation of steel plate, hysteresis loops, interaction with the surrounding frame, several configurations of SPSWs with thick plates, stiffened or un-stiffened thin steel plates, etc., have made them still attractive for more investigation. This paper presents shear strength capacities and proposes relevant formulas for SPSWs with and without stiffeners with considering effects of the relative stiffness and strength of the boundary elements on the shear capacities. Several analytical finite element models with different h/t of steel plate are considered and kinematic hardening model is used for steel material, non-linear large-displacement analysis under monotonic loading has been carried out and their push-over curves obtained. The results are compared with the experimental studies by other researchers and codes regulations. The theoretical and analytical studies indicate that the shear strength capacities of SPSW vary between results from using the plate girders simulation model for SPSW and the strip model, and depend on the relative stiffness and strength of the boundary elements as well as the slenderness of the infill steel plate.
