| 摘 要： | 采用ANSYS软件对钢框架-冷弯薄壁墙体结构进行有限元数值分析，得到该体系在单调水平荷载作用下的变形和应力分布，研究此体系的抗侧承载能力和抗侧刚度，分析钢框架与内填冷弯薄壁墙体之间的相互作用、协同工作性能和抗侧能力的分配。研究表明，钢框架-内填冷弯薄壁墙体结构具有较高的抗侧刚度和抗侧承载能力，其延性性能优良，是-种理想的双重抗侧力体系，可用于多层或小高层钢结构住宅，作为结构的抗侧力构件。

| Abstract: | A finite element simulation analysis was conducted with the specimens of steel frame-cold formed steel stud composed wall subjected to shear load by ANSYS. The deformation and stress distribution of the structure was obtained. The lateral bearing capacity and the lateral stiffness were studied. Meanwhile, the interaction and the distribution of shear force between the steel frame and the cold formed steel stud composed wall and the coordinated working performance of the structure were analyzed. It was indicated that the lateral bearing capacity and the lateral stiffness of steel frame-cold formed steel stud composed wall was evidently improved, which has excellent ductility and which is a kind of ideal dual lateral force resisting system. |
