This paper presents the results of evaluating the effects of the location and size of rectangular opening on the cyclic performance of steel plate shear wall (SPSW) systems through an experimental study. A total of seven 1:6 scale SPSW specimens were tested under quasi‐static cyclic loads. Apart from a solid (without opening) specimen, six specimens with different opening locations and sizes were considered. The rectangular opening in the SPSW specimens with the relative opening‐to‐plate area of 4.00, 6.76% and 10.24% caused a reduction in maximum shear capacity by 28%, 33%, and 46% respectively. A similar trend was also noticed in the reduction of initial stiffness. The test results proved good performance of the stiffeners around the opening perimeter in preventing the zipping of the plate at these regions. However, from the drift ratio of 1.0%, the tearing of the plate began gradually and was followed by significant strength degradation. Because of the buckling and snap‐back of the plate, pinching in force‐displacement of all the specimens was observed. Also, a finite element simulation of all the specimens was performed, which led to acceptable results in terms of the characteristics of force‐displacement response.

单矩形开口钢剪力墙的试验循环性能

通过实验研究，本文介绍了评估矩形开口的位置和大小对钢板剪力墙（SPSW）系统循环性能的影响的结果。在准静态循环载荷下测试了总共七个1：6比例的SPSW标本。除了实心（无开口）样本外，还考虑了六个具有不同开口位置和大小的样本。SPSW样品中的矩形开口相对于板的相对开口面积为4.00、6.76％和10.24％，导致最大剪切能力分别降低了28％，33％和46％。在初始刚度的降低中也发现了类似的趋势。测试结果证明了加强筋在开口周边周围的良好性能，可以防止板在这些区域发生拉锁。但是，从1.0％的漂移率来看，钢板的撕裂逐渐开始，随后强度明显下降。由于板的屈曲和弹回，观察到所有样品的力位移都发生了收缩。此外，对所有样本进行了有限元模拟，这在力-位移响应特性方面得出了可接受的结果。
