摘　　要：通过改变半刚性连接的轻钢龙骨隔墙体系中龙骨数量、龙骨截面尺寸和外覆OSB板厚度,利用ABAQUS有限元软件建模并对模型施加单调荷载以及低周往复循环加载,获得其刚度、承载力以及滞回曲线.结果表明:随着竖向龙骨间距降低以及厚度增大,半刚性钢框架-轻钢龙骨隔墙体系刚度及承载力逐渐增加,但增加的速率减缓,且龙骨间距过小对体系承载力提高不显著且不经济;而OSB覆板厚度对结构抗侧力有提高,但对耗能性能影响不大;龙骨截面尺寸增大对结构性能影响显著,用钢量不变只改变截面惯性矩可以改善结构性能,该方法经济性最好.ABAQUS finite element software is used to set up the model and monotonic and cyclic load is applied to it.The quantity,the size of cross section and the thickness of coated OSB plate of semi-rigid steel frame with light steel keel wall are changed to obtain the stiffness,bearing capacity and hysteretic curve.The results show that with the vertical keel spacing decreasing and the thickness increasing,the stiffness and bearing capacity of semi-rigid steel frame with light steel keel wall system gradually increased,but at a decreasing rate.Besides,too small keel spacing does not lead to obvious improvement of system capacity and is not economical.Increasing the thickness of OSB plate has little effect on the performance of energy consumption but improves the force of bearing capacity.The size of cross section has significant effect on system performance.Increasing the section inertia moment while maintaining the steel quantities is the best way to achieve economy.
