| 摘 要： | 为了获得冷弯型钢骨架墙体最大受剪承载力实用计算公式,提出了墙体在水平力作用下的两种可能破坏模式,即边立柱在抗拔连接件处的净截面破坏和墙体周边或墙板拼缝处大多数自攻螺钉连接破坏。根据墙体破坏模式提出了相应的最大受剪承载力计算模型,并结合试验数据和有限元结果,得到了单面覆石膏板墙体、单面覆OSB板墙体和单面覆带肋钢板墙体最大受剪承载力实用计算公式,公式计算结果同试验、有限元分析结果吻合较好。最后,给出了冷弯型钢骨架墙体受剪承载力实用计算公式应用算例,以供设计参考。

| Abstract: | To obtain practical calculation formulae of the lateral stiffness of cold-formed steel framing walls,the simplified calculation model of the lateral stiffness of cold-formed steel framing walls is suggested by simplifying the wallboards as inclined tension and compression rods and the other assumptions.The theoretical calculation formula of the lateral stiffness of walls is proposed based on the elastic analysis,and further modified by considering elasto-plastic effects using test data and finite element an... |
