摘　　要：装配式灌芯混凝土剪力墙是一种新型装配式剪力墙,在地震作用下受力和破坏机理复杂,故准确模拟其受力与破坏过程对于结构抗震分析具有重要意义。利用数值模拟技术,在已有试验研究基础上,对装配式灌芯混凝土剪力墙进行有限元模拟计算,并与试验骨架曲线和裂缝分布进行对比,系统地分析轴压比、边缘构件配筋率和墙身配筋率对装配式灌芯混凝土剪力墙受力性能的影响及其规律。分析结果表明,模拟计算结果与试验结果吻合良好;轴压比对剪力墙受力性能影响显著;边缘构件配筋率和墙身配筋率影响剪力墙的延性,对极限承载力影响不大。Precast shear wall with core grouted concrete is a new type of precast shear wall, whose seismic performance is complicated.Therefore, how to accurately simulate the nonlinear behaviors of this precast shear wall is important for seismic analysis of structure.Basedon the existing experimental data and numerical simulation technique, finite element model of precast shear wall with core grouted con-crete is established reasonably.Then the influence of axial compression ratio and reinforcement ratio of edge members and wall body is an-alyzed systematically.The results of simulation match well with the experiment.Axial compression ratio has significant influence on me-chanical performance and reinforcement ratio of edge members and wall body influence the ductility except bearing capacity.
