Analyses on Seismic Behavior of Corrugated Steel Plate Shear Walls

Corrugated Steel Plate Shear Wall (CoSPSW) is a new type of lateral load resisting system in which corrugated steel wall panels are embedded inside boundary frames, with the corrugation oriented in the horizontal or the vertical direction. Corrugation will form “ribs” on the wall panel, and the axial and out-of-plane bending stiffness is greatly enhanced along the direction parallel to the rib, while the axial stiffness will become minimum along the direction perpendicular to the rib, which is called “According Effects”. As a result, wall panels with vertical ribs or vertical corrugation will be able to resist the gravity loads transferred to them due to enhanced vertical buckling capacity, while wall panels with horizontal ribs or horizontal corrugation will neatly avoid the gravity loads transferred to them. Compared with the unstiffened steel plate shear walls (SPSW), CoSPSWs 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 wall 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 capacity 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 almost no pinching. Accordingly, shear walls with weak frame or under gravity loads are studied. When a weaker frame is used, tension field action of the SPSWs cannot fully develop, which causes 18% and 25% reduction in the ultimate lateral strength and energy dissipation. While CoSPSWs is less sensitive to the frame stiffness compared to the SPSWs, especially the vertical CoSPSWs. When gravity loads are applied, the ultimate lateral strength of the wall panels in the SPSWs had a significant reduction of 38%; CoSPSWs is less sensitive to the gravity load effects compared to the SPSWs.
