摘要以往对钢板剪力墙（SPSWs）的研究和现行设计规范主要集中在通过严格的细节要求实现高延性行为。因此，该系统通常被认为仅在高地震区域是经济的。然而，其他区域的需求较低，可能允许使用更经济的选择。本文介绍了一个建议的概念SPSW，满足能力设计的意图，同时大大提高了在地震区的最大延性是不需要的竞争力。一个大规模的，2层SPSW标本进行了测试，以评估相关的性能。墙有标准的双角梁柱剪力连接，并在垂直重力荷载下进行测试，同时在每个楼层进行反向横向荷载。样本经受住了25次侧向载荷循环，其中18次处于非弹性范围。试验结果表明，尽管存在显著的缺陷，但在低地震区仍能获得良好的性能。
AbstractPrevious research on steel plate shear walls (SPSWs) and current design codes have focused principally on achieving highly ductile behavior through stringent detailing requirements. As such, the system is generally considered to be economical only in high-seismic regions. However, lower demands in other regions may permit the use of more economical options. This paper describes a proposed concept for SPSWs that meets the intent of capacity design, while greatly improving competitiveness in seismic regions where maximum ductility is not required. A large-scale, 2-story SPSW specimen was tested to evaluate the associated performance. The wall had standard double-angle beam-to-column shear connections and was tested under vertical gravity load concurrent with reversing lateral loads at each floor level. The specimen survived 25 lateral load cycles, 18 of which were in the inelastic range. The test results indicated that excellent performance can be expected in low-seismic regions, despite significant...
