近些年钢结构住宅体系得到了很快的发展，对钢结构墙体的研究也逐渐深入。运用有限元软件模拟刚性连接的钢框架与轻钢龙骨的组合结构体系，研究其抗侧力性能。对变化轻钢龙骨隔墙形式的3组模型进行低周往复加载数值模拟，得到其滞回曲线、骨架曲线、承载力、初始刚度及结构的耗能性能，对比分析了轻钢龙骨隔墙及钢框架的连接方式对墙体的影响。模拟结果表明：龙骨外加蒙皮大幅度增加了墙体的承载能力、结构刚度；结构承载力及刚度由轻钢龙骨与蒙皮之间的连接构件强度确定；刚性连接钢框架的初始刚度及承载力高于半刚性连接钢框架。

In recent years ,the residential building system of steel structure has obtained great development ,and the re-search about the steel structure wall is also carried out gradually and deeply .The structure composed of steel frame and light steel keel was simulated by finite element software to study the lateral -force-resistance behavior .The numerical sim-ulation of low-cycle reciprocating load was made for 3 groups of different steel frame with light steel wall ,the hysteresis curves ,skeleton curves ,bearing capacity ,initial stiffness and energy dissipation capacity of the structure system were obtained ,and the influences of the connection from of the light steel keel wall and steel frame on the wall were analyzed . The simulation results suggest that the iron skin added to the outside surface of keel wall can significantly increase the stiffness and bearing capacity of the structure .The strength of the connection between the steel keel and iron skin can de-termine the capacity and stiffness of the structure .The initial stiffness and bearing capacity of the steel frame with rigid connection are higher than those with semi-rigid connection .
