【摘要】：以16个不同参数的带约束拉杆的双钢板混凝土组合剪力墙滞回加载试验为基础,研究了不同高宽比、轴压比以及不同约束拉杆间距的组合剪力墙破坏模式,得到了试件的滞回曲线、承载力、骨架曲线以及位移延性等抗震性能参数,并通过数值计算其与普通钢筋混凝土剪力墙的对比,分析得出组合剪力墙具有比普通剪力墙更好的承载力和延性。同时采用ABAQUS有限元软件对双钢板混凝土组合剪力墙结构和普通混凝土剪力墙结构进行不同地震作用水平的弹塑性时程分析,对比了二者的层间位移角及构件的塑性耗能,结果表明较之普通混凝土剪力墙,组合剪力墙可以有效的减小结构的层间位移角,降低剪力墙的塑性耗能,提高连梁的耗能比例,对结构抗震更为有利。
[Abstract]:Based on the hysteretic loading tests of 16 double steel plate concrete composite shear walls with different parameters, the failure modes of composite shear walls with different aspect ratio, axial compression ratio and constraint bar spacing are studied. The seismic performance parameters such as hysteretic curve, bearing capacity, skeleton curve and displacement ductility are obtained, and the numerical results are compared with those of ordinary reinforced concrete shear wall. It is concluded that the combined shear wall has better bearing capacity and ductility than the ordinary shear wall. At the same time, the ABAQUS finite element software is used to analyze the composite shear wall structure and the ordinary concrete shear wall structure. Elastoplastic time-history analysis with the same earthquake action level. The results show that the combined shear wall can effectively reduce the interstory displacement angle of the structure and reduce the plastic energy dissipation of the shear wall compared with the ordinary concrete shear wall. Increasing the energy consumption ratio of the connecting beam is more favorable to the seismic resistance of the structure.
