多腔钢板-混凝土组合剪力墙抗震性能研究

ASEISMIC BEHAVIOR OF COMPOSITE SHEAR WALL WITH STIFFENED DOUBLE STEEL PLATES AND INFILLED CONCRETE

  • 摘要: 为研究高层或超高层大楼中拟采用的多腔钢板-混凝土组合剪力墙的抗震性能,对其进行拟静力试验及有限元模拟,分析了腔数对该类组合剪力墙的破坏模式、承载力、滞回曲线、骨架曲线、延性、刚度退化及耗能能力的影响。试验现象表明试件的破坏模式均为上部混凝土压碎、角部钢板屈曲。通过分析试验结果发现,该种类形式的组合剪力墙在较高轴压力作用下仍具有良好的水平变形能力和较强的耗能能力,3个试件的极限位移角平均值为1/61,且单腔长宽比的减小会降低试件的承载力、增加试件延性。通过有限元软件建立的该类组合剪力墙模型证明该计算结果与试验值吻合良好,同时发现当单腔长宽比减小到1.94时,组合剪力墙的极限承载力基本不变。

     

    Abstract: In order to study the aseismic behavior of shear walls in super high-rise buildings, the quasi-static test and finite element analysis on steel plate-concrete composite shear walls were conducted. The research focused on the effect of cavity on the aseismic performance, which included failure mode, bearing capacity, hysteresis curves, skeleton curves, ductility, rigidity degeneration and energy dissipation capacity. All specimens failed in the same failure mode, characterized by concrete crushing at the upper wall and local buckling of the steel plate in the corner. The results indicated that the composite shear wall exhibited excellent inter-storey deformation capacity and energy dissipation under high axial forces. The average value of the ultimate drift ratios for all the specimens was 1/61, and bearing capacity decreased with the decrease of length to width ratio of a single tube. A finite element model developed by ABAQUS is used to simulate the performance of this type of composite shear wall and the accuracy of the model is validated through the comparison with the experiment results. Meanwhile, it has been found that the ultimate bearing capacity of the composite shear wall is not significantly affected until the length to width ratio of a single tube decrease to 1.94.
