摘　　要：基于4个高强混凝土剪力墙试件在低周往复水平荷载作用下的抗震性能试验结果,利用有限元软件ABAQUS,选用合适的拉、压损伤本构关系以及单元模型,建立高强混凝土剪力墙的有限元模型,模拟其加载全过程和受力性能,模拟滞回曲线与试验滞回曲线吻合较好。在此基础上,采用相同的有限元模型和材料损伤本构关系,分析影响高强混凝土剪力墙抗震性能的主要因素,包括轴压比、约束边缘构件的配箍特征值、混凝土强度和边柱纵筋配筋率,研究影响剪力墙抗震性能参数的限值并给出其范围。Based on the seismic experiments of 4 high-strength concrete shear walls（HSCW） under cyclic loading, the nonlinear analysis was performed to simulate the complete loading and mechanical behavior by using the finite element software ABAQUS. The nonlinear characteristic of material, including a set of element models and damage constitutive relation of tensile and compress, was taken into account in the models. The reliability of the finite element model was verified by the comparison between analysis results and experimental results. Through the proposed numerical model, in the consideration of the effect of the axial load ratio, stirrup ratio, concrete strength and ratio of reinforcement, the allowable value of parameters and its range are suggested.
