摘要
对组合墙体抵抗水平剪力的受力机理进行了分析研究,在借鉴传统木结构房屋组合墙体侧向力作用下变形的研究基础上,文中采用整体受力分析法计算每个自攻螺钉的受力和采用线性插值来计算每个自攻螺钉的滑移位移.利用虚功原理提出了冷弯薄壁型钢组合墙体的刚度计算公式及建议.可供实际工程设计参考.
The capacity of shear behavior of composite wall to resist horizontal load is the major concern in this paper. Referring to the research on the traditional wooden structure composite wall＇s deformation caused by the lateral load, the methods of overall force analysis and linear interpolation are employed to calculate respectively the force of each screw and each self - drilling screw slip. A formula for the cold - formed steel wall lateral stiffness and some recommendations are proposed by adopting the virtual work principle, which is referential to the practical engineering design.
