摘要：

Two types of lateral resistance structural systems, namely unstiffened steel plate shear walls (USPSWs) and stiffened steel plate shear walls (SSPSWs), are typically used in high-rise structures. Numerous experimental and numerical studies have been conducted on the structural performance of SSPSWs. However, few studies have been conducted to investigate the effect of column flexural stiffness on SSPSW systems. In this study, an analysis and numerical investigation of SSPSWs with variable column flexural stiffnesses was performed. The hysteretic performance, secant stiffness reduction and energy dissipation of SSPSWs with four column flexural stiffnesses were investigated. The column flexural stiffness reduction in the USPSWs and SSPSWs did not negatively influence the overall performance of drift ratios up to 2.5%. Moreover, the infill plates of the USPSWs and SSPSWs could achieve the ultimate strengths similar to the theoretical values despite the column not satisfying the minimum flexural stiffness requirements from CSA S16-09 and PEER/ATC72-1, which indicated that these requirements could be conservative.
