Corrugated Steel Plate Shear Walls (CoSPSW) are lateral load resisting system in which corrugated steel plates are embedded inside a boundary frame, with the corrugation oriented in the horizontal or the vertical direction. Corrugated Steel Plate Shear Wall is a new type of lateral load resisting system in the family of steel plate shear walls. Compared with the unstiffened plane steel plate shear walls (SPSW), CoSPSW would have greater elastic buckling capacity, and more resistance to the gravity loads transferred to the wall panel or neatly avoid them depending on direction of the corrugation. The main focus of this paper is on the seismic behavior of CoSPSWs and comparison with SPSWs. Nonlinear push-over and cyclic analyses were conducted on a group of 3D CoSPSW and SPSW models, and parametric studies were performed with different panel and frame configuration, as well as gravity load effects. It turns out that CoSPSWs with deeper corrugation have higher lateral stiffness, lateral strength and energy dissipation than SPSWs; while CoSPSWs with shallower corrugation have higher lateral stiffness and ductility, but lower lateral strength than SPSWs. For all cases investigated, CoSPSWs have stable hysteric curves with no almost pinching, and they are much less sensitive to the influence of gravity loads or weaker boundary frames, compared with SPSWs.
