Corrugated steel plate shear walls (CoSPSWs) consist of corrugated steel wall plates and a steel boundary frame, which could be adopted as seismic-resistant systems for high-rise buildings. In this study, a performance-based seismic design (PBSD) method was proposed for CoSPSWs, in which an ideal yield mechanism and target drifts were selected as performance objectives to evaluate and control the inelastic behavior of the system. Two 10-story CoSPSW structures were then designed with the PBSD method and the traditional method respectively, and static pushover analyses as well as nonlinear dynamic time-history analyses were conducted on both structures. It turned out that the CoSPSW structure designed with the PBSD method presented the ideal yield mechanism, all inter-story drifts were well below the target drift of 2.5%, and the drifts distributed more smoothly under rare earthquakes. Structural and nonstructural fragility curves of both CoSPSW structures were obtained through probabilistic seismic demand analysis using Incremental Dynamic Analyses. The results showed that for the structural repair states of RS1 to RS5, the 25th percentile PGA values of the fragility curves of the CoSPSW structure designed with the PBSD method were 220%, 98%, 84%, 51 % and 13% higher than the CoSPSW structure designed with the traditional method, respectively. For the nonstructural damage states of Slight to Complete, the 25th percentile PGA values of the fragility curves of the CoSPSW structure designed with the PBSD method were 145%, 98%, 36%, and 7% higher than the CoSPSW structure designed with the traditional method, respectively. Therefore, CoSPSW structure designed with the PBSD method had lower seismic vulnerability as well as probability of nonstructural damage.
