Abstract
This paper proposed a light-weight buckling restrained steel plate shear wall (XSPSW) to improve the earthquake energy dissipation of unstiffened steel plate shear walls. It consisted of two slidable multiple X-shaped restrainers placed on the either side of a steel infill plate. The two restrainers could continue to provide out-of-plane restraint for infill plates to achieve stable energy dissipating capacity under cyclic reversal loads. Theoretical analyses and numerical simulating analyses have been conducted to investigate the hysteretic behaviors of XSPSWs and the stability of their sub-plates. Based on the analysis results, it could be concluded that the proposed XSPSWs were efficient lateral-load resisting members for the buildings in high seismic regions.
