世界上已有几种结构采用钢板剪力墙作为主要的抗侧荷载体系。它代表了一种创新技术，为中高层钢结构提供高弹性强度、大位移延性和良好的耗能性能，在高地震风险地区尤为重要。在不列颠哥伦比亚大学对两个单层和一个多层钢板剪力墙组件进行了试验测试。每个样本包括一个单独的海湾，30%比例的内部住宅建筑核心模型，面板宽度与高度长宽比为1:1。每个试件都采用抗矩梁柱连接，以及与周围框架完整周长连接的薄无加劲填充板。准静力循环试验是在确定钢结构抗震性能的标准试验协议下进行的。测试程序的主要目标是确定载荷变形响应特性和各种部件的应变分布。三个试件的最大位移延性分别为7 × 5^、6 × 5^和1.5 × 5^。每次测试的终止都是局部问题和测试设置限制的结果，并不一定反映全局
Several structures around the world have been designed with steel plate shear walls acting as the primary lateral load resisting system. It represents an innovative technique for providing high elastic strength, large displacement ductility capacity, and good energy dissipation properties in medium and highrise steel structures, which is of particular importance in areas of high seismic risk. An experimental testing programme was conducted at the University of British Columbia on two single and one multistorey steel plate shear wall assemblies. Each specimen consisted of a single bay, 30 % scale model of an inner residential building core with panel width to height aspect ratios of 1:1. Each specimen employed momentresisting beam column connections, and thin unstiffened infill panels with full perimeter attachment to the surrounding frame. Quasi-static cyclic testing was conducted under standard testing protocols used to determine the seismic performance of steel structures. The determination of the load deformation response properties and resulting strain distribution in various components were the primary objectives of the testing program. The three test specimens were tested to maximum displacement ductilities of 7x5^ , , 6 x 5^ , and 1.5 x 5^ respectively. The termination of each test was a result of local problems and limitations of the testing setup, and did not necessarily reflect the global
