半刚接钢框架-轻钢龙骨隔墙体系性能研究

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.
