摘　　要：为了获得冷弯型钢骨架墙体抗侧移刚度实用计算公式,将墙体墙面板等效为拉压斜杆,并基于其他一些基本假定提出了冷弯型钢骨架墙体抗侧移刚度简化计算模型,在弹性分析的基础上得到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进行了弹塑性修正,得到单面覆石膏板墙体、单面覆OSB板墙体、单面覆带肋钢板墙体在水平风荷载、水平多遇、水平罕遇地震作用下抗侧移刚度实用计算公式,墙体抗侧移刚度实用计算公式计算结果与试验、有限元分析结果吻合较好。同时,提供了冷弯型钢骨架墙体抗侧移刚度实用计算公式应用算例,以供设计参考。To obtain simplified calculation practical calculation formulae of the lateral stiffness of model of the lateral stiffness of cold-formed steel framing wallboards as inclined tension and compression rods and the other assumptions cold-formed steel framing walls, the walls is suggested by simplifying the 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 analysis results. The practical calculation formulae of the lateral stiffness are proposed for three types of walls including single gypsum wallboard, single OSB （ oriented strand board） and single steel rib panel, under the horizontal wind load, the horizontal frequent earthquake and the horizontal rare earthquake. The calculation results of the practical calculation formulae of the lateral stiffness of walls agree well with experimental data and finite element results. The paper also provides an example of the practical calculation of the lateral stiffness of cold-formed steel framing walls for design reference.
