摘　　要：灌芯装配式混凝土大板剪力墙是一种新型装配式剪力墙,能够大幅度降低工程造价,具有广阔的市场前景,故对该种形式剪力墙的抗震性能的研究具有重要意义。本文利用ABAQUS有限元分析软件对灌芯装配式混凝土大板剪力墙进行了数值模拟,将模拟结果和试验骨架曲线、试验过程中墙体破坏形态进行了对比分析。同时,系统分析了轴压比、边缘构件配筋率、墙身配筋率以及墙身底部水平钢筋的间距对灌芯装配式混凝土大板剪力墙受力性能的影响。分析结果表明:模拟计算结果与试验结果吻合;轴压比、边缘构件配筋率能显著影响构件的承载力和变形能力;墙身配筋率、墙身底部水平钢筋的间距对构件无显著影响。Fabricated core grouted concrete large panel shear wall is a new type of prefabricated shear wall. It can greatly reduce the project cost, so it has a broad market prospect. Therefore the study of seismic behaviors of this form of shear wall is of great importance. In this paper numerical simulation was made for ABAQUS to fabricated core grouted concrete large panel shear wall, simulation results and experiment skeleton curve, the process of wall failure pattern were analyzed. At the same time systematic analysed the impact of axial compression ratio, reinforcement ratio edge components, wall body steel reinforcement ratio and the spacing of horizontal reinforcing steel bar at the bottom of the wall of the mechanical behavior of fabricated core grouted concrete large panel shear wall. The analysis results show that the simulation results match up the test results. Axial compression ratio, reinforcement ratio edge components can significantly affect the bearing capacity and deformation capacity of components. Wall body reinforcement ratio and the distance between the horizontal reinforcing steel bar at the bottom of the wall body have no significant effect on the component.
