摘　　要：针对设计的双层预制钢管混凝土剪力墙及墙体截面中等距离设置的钢管,利用ABAQUS建立有限元模型,对比分析了普通钢筋混凝土剪力墙与钢管混凝土剪力墙之间承载能力与变形能力的差别.结果表明,钢管对内部混凝产生围压作用形成暗柱,提高了剪力墙的承载能力与变形能力,并在此基础上分析轴压比和钢管材料强度对钢管混凝土剪力墙受力性能的影响.Aiming at the double-layer prefabricated concrete filled steel tubular shear wall and the steel tube with middle distance section,the finite element model was established by ABAQUS,and the difference of bearing capacity and deformation capacity between the ordinary reinforced concrete shear wall and the concrete filled steel tubular shear wall was compared and analyzed.The results show that the confining pressure of steel tube on the internal coagulation results in the formation of concealed columns,which improves the bearing capacity and deformation capacity of the shear wall.On this basis,the influence of axial compression ratio and steel tube material strength on the mechanical behavior of concrete filled steel tubular shear wall is analyzed.
