摘要

摘要: 通过对不同轴压比的3片墙体试件的拟静力试验，对桁架式多腔体钢板组合剪力墙的破坏模式、承载能力、刚度退化、耗能能力、整体水平变形及剪切变形等进行了探究和分析。结果表明：此组合剪力墙承载力较高并具有良好的延性和耗能能力；高宽比为2.0时，试件的破坏特征以钢板局部剪切屈曲、端柱钢管压屈和撕裂以及混凝土压碎为主，试件的剪切变形占整体水平变形的20%~40%，试件均发生了剪压破坏；轴压比对试件的抗剪承载力和刚度退化的影响较小，轴压比较小时试件具有较好的延性。

Abstract: Based on the quasi-static tests of three wall specimens with different axial compression ratios, the failure modes, bearing capacity, stiffness degradation, energy dissipation capacity, lateral deformation and shear deformation of the double-skin multi-cavity composite wall with steel truss were explored and analyzed in the paper. The results showed that the innovative double-skin composite wall with steel truss had better bearing capacity, ductility and energy dissipation capacity. When the aspect ratio was 2.0, the main failure characteristics of the specimens were local shear buckling of steel plates, fracture and buckling of steel tubes, and compressive crushing of concrete. The shear deformation accounted for 20% to 40% of the overall lateral deformation, and all specimens were damaged in shear-compression mode. The effect of axial compression ratio on the horizontal bearing capacity and stiffness degradation of the specimens was small, and the specimens with small axial compression ratio showed better ductility.
