| 摘 要： | 进行了2块双面无板带交叉扁钢拉条支撑的冷弯型钢骨架墙体足尺试件(宽2.4m,高3m)抗剪试验。利用提出的墙体抗侧移刚度简化计算模型推导了墙体抗侧移刚度理论计算公式,并结合试验数据和有限元分析结果,得到墙体抗侧移刚度实用计算公式,公式计算结果与试验、有限元分析结果吻合较好;通过对墙体在水平力作用下的各种可能破坏模式的研究,提出了相应的墙体最大抗剪承载力计算模型,并结合试验和有限元结果,得到了墙体最大抗剪承载力实用计算公式,公式计算结果同试验、有限元分析结果比较一致。

| Abstract: | The shear performance of two full-size(2.4m by 3m) specimens of cold-formed steel framing wall with steel X-strap bracing on both sides was studied by test.The simplified calculation model of the lateral stiffness of walls was put forward to deduce the theoretical calculation formula of the lateral stiffness of walls.Combining with test data and finite element analysis results,the practical calculation formula of the lateral stiffness of walls with steel X-strap bracing on both sides was proposed.And the ca... |
