摘要

本文以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

On the basis of tests for sixteen different specimens of composite concrete and doublesteel plate shear walls with binding bars, the failure modes of specimens with different aspect ratios, axial compression ratios and distances between binding bars were observed, and some valuable results were obtained for the specimens hysteretic loops, forcebearing capacity，skeleton curves and displacement ductility．The tested specimens aseismic parameters were compared with those of the traditional reinforced concrete walls using numerical analysis. The results indicated that the composite shear walls have better aseismic performances. Simultaneously the elastic-plastic time history analyses under different earthquake levels were conducted for both composite shear wall structural systems and traditional reinforced concrete shear wall systems with ABAQUS to compare their drift ratio and components plastic energy dissipation. The results demonstrated that the composite shear wall systems drift ratio and plastic energy dissipation are significantly reduced, and the energy dissipation capability of connected beams increases; the aseismic behavior of composite shear wall structure systems is better than that of traditional shear wall systems. 
