摘　　要：轻钢骨混凝土剪力墙结构作为新型结构在工程界要得到认同并推广使用,必须对该结构的各项性能指标进行系统的试验研究和理论分析。本文应用ADINA有限元软件对轻钢骨混凝土剪力墙延性进行非线性有限元分析,根据不同的高宽比、轴压比、轻钢骨配筋率以及端部配筋模型的计算结果,对该结构体系的延性及其破坏形态进行综合分析,并对轻钢骨混凝土剪力墙轴压比设计提出建议。分析结果表明,高宽比主要控制轻钢骨混凝土剪力墙的破坏形态,轴压比对其结构的延性的影响最为显著,而端部配筋对其延性影响不大。Light steel-reinforced concrete shear wall, as a new structural system, must be gone along systematie test research and theory analysis of its mechanic behavior in order to be accepted and used. This paper studies ductility of light steel reinforced concrete shear wall and nonlinear finite element analysis is completed using ADINA software. Based on the calculation results of models with variable height-width ratio, axial compression ratio, steel reinforced ratio and reinforcement steel at the end of shear wall, ductility and destruction forms are comprehensively analyzed, and design suggestions are given to axial compression ratio of light steel-reinforced concrete shear wall. The results indicate that the height-width ratio controls the destroying form of the wall, the axial compression ratio affects its ductility and the reinforcement steel at the end of shear wall has less effect on it.
