提出一种适用于钢框架结构体系的新型组合钢板剪力墙单元,它由三边固接一边弹性约束的钢板和预制水泥基覆板组合而成。通过三种钢板宽厚比的纯钢板剪力墙和组合钢板剪力墙共6个试件的静力加载试验,考察宽厚比对三边约束钢板受剪承载力的影响,同时考察分析预制水泥基覆板对内嵌钢板的屈曲承载力和受剪承载力的影响。试验结果表明:宽厚比决定了钢板初始抗侧性能和屈曲模态;预制水泥基覆板对提高剪力墙单元受剪承载力和钢板屈曲承载力有一定帮助;通过有效抑制内嵌墙板的面外屈曲,可以提高组合钢板剪力墙单元的抗震性能。
A new type of composite steel plate shear wall unit suitable for steel frame structure system is proposed, which is composed of steel plates with elastic restraint on three sides and precast cement base plate. Through the three kinds of steel plate thickness ratio of the pure steel plate shear wall and the combination of steel shear wall of a total of six specimens static load test to investigate the aspect ratio of the trilateral restraint steel shear capacity, while the analysis of precast cement-based Effect of Sheeting on Buckling Capacity and Shear Capacity of Embedded Steel Plates. The test results show that the aspect ratio and the buckling mode of the steel plate are determined by the aspect ratio, and the precast concrete subbase plate is helpful to improve the shear capacity of the shear wall element and the buckling capacity of the steel plate. Out-of-plane buckling can improve the seismic performance of composite shear wall elements.
