摘　　要：为研究不同轴压比下钢管混凝土剪力墙结构的受力性能,首先进行了3片双层单跨钢管混凝土剪力墙拟静力试验,端柱底部钢管屈服破坏,利用有限元软件ABAQUS建立试件数值模型,计算结果与试验吻合良好,在此基础上,通过对9组轴压比从0~0.8的钢管混凝土和钢筋混凝土剪力墙单调推覆分析,深入探讨了试件的承载力、延性系数及钢管端柱对墙体整体性能的影响。In order to study the mechanical behavior of steel tube-reinforced concrete composite shear walls, three specimens subjected to cyclic lateral loading was tested. The test results indicate that the specimen fail in local buckling of boundary steel tube. Finite element model was constructed and validated by comparisons with test data. Monotonic pushover analyses were performed through nine steel tube-reinforced concrete composite shear walls and nine steel-reinforced concrete shear walls with axial-load ratios from 0 to 0.8, to investigate the effects of lateral bearing capacity, ductility coefficient and steel tubes on mechanical behavior of composite coupled wall.
