提出一种适用于钢框架结构体系的新型组合钢板剪力墙形式。对4种宽厚比的纯钢板和1种组合钢板剪力墙单元的静力加载试验的结果表明:宽厚比决定了钢板初始抗侧性能和屈曲模态;小宽厚比钢板对边界约束条件较为敏感;预制墙板对提高剪力墙单元抗剪承载力和提高屈曲荷载有一定帮助,但是对钢板抗侧性能的贡献不大。通过数值模拟增加影响参数,对新型组合钢板剪力墙单元进行了理论分析。最后给出了三边固接一边弹性约束的钢板及组合钢板剪力墙单元的抗剪承载力计算公式,并依据成品预制墙板的规格尺寸给出了组合钢板剪力墙适用的预制墙板最小厚度选择方法。
A new type of combined steel plate shear wall suitable for steel frame structure system is proposed. The results of static loading tests on four kinds of pure steel plates with one aspect ratio and one kind of composite steel plate shear wall elements show that the aspect ratio and the buckling mode determine the aspect ratio and the buckling mode. The prefabricated wall panels have some help to improve the shear strength of the shear wall elements and improve the buckling load, but they have little contribution to the anti-side performance of the steel plates. Through the numerical simulation to increase the influence parameters, the theoretical analysis of the new composite steel plate shear wall element is made. Finally, the formulas for calculating the shear strength of steel plates and composite steel shear wall units with three sides fixed are given. According to the dimension of finished prefabricated wall panels, the prefabricated wall panels Minimum thickness selection method.
