摘　　要：根据组合墙钢板的剪切破坏先于屈曲变形发生的原则,提出新型钢框架-组合墙结构的设计方法,经对结构的破坏机理进行理论分析,提出基于塑性理论的侧向极限承载力的计算方法;利用ANSYS建立非线性有限元分析模型,对结构模型的理论塑性破坏模式进行验证;将有限元分析结果与塑性理论值进行比较,结果表明,塑性分析方法可用于预测结构侧向极限承载力,安全储备约为9.4%。According to the phenomenon that the shear failure of composite steel plate shear walls precedes their buckling deformation,we put forward a desgin method for the new style steel frame-composite steel plate shear wall,theoretically analyze its failure mechanisms,and propose a calculation method of its lateral limit bearing capacity based on the theory of plasticity.A non-linear finite element model is set up using ANSYS software to verify the plastic damage model of the steel frame.By comparison of plastic theoretical results and finite element results,it is shown that the plastic anlysis method is feasible,and the safety reserve is 9.4%.
