Research on Seismic Performance of Corrugated Steel Plate Shear Walls with Inelastic Buckling Subjected to Lateral Loads

The corrugated steel plate shear wall (CSPSW) with inelastic buckling of a corrugated steel plate (CSP) could restrict the elastic out-of-plane buckling of in-filled steel plates with appropriate CSPs, and lateral displacement could be restricted in the structures. So, the CSPSWs with inelastic buckling of CSPs could be applicable in high buildings or the structures with strict requirements of lateral displacement. This paper presents the research works on the seismic behaviour of the CSPSW with inelastic buckling of a corrugated steel plate. A numerical model was developed to simulate the seismic performance of the CSPSW with the inelastic buckling of the CSP, and the FE model was validated through experiment. Subsequently, parametric analyses were performed to investigate for the effects of those key parameters on the seismic behaviour of CSPSWs, such as the height—thickness ratio, aspect ratio, horizontal panel width, corrugation angle, initial imperfections, and surrounding frame stiffness. The buckling and post buckling behaviour, failure modes, ductility and energy absorption capacity of the shear walls were discussed. The results reveal that the CSPSW show high strength, better ductility, and stable hysteretic characteristics. The failure modes of the CSPSWs with CSPs inelastic buckling are the failure of the tension field strips along the along the diagonals in the whole CSPs. And the corners of CSPs in CSPs are weak parts, which should be strengthened in future designs. Besides these, the surrounding frame stiffness should be greater than I c min to ensure energy-dissipating capacity and buckling capacity stability of CSPSWs.
