    摘要：配筋砌块砌体剪力墙结构具有传统砌体结构和钢筋混凝土结构的共同优点，在我国建筑领域中得到了广泛应用。在构建混凝土本构有限元模型后，运用Abaqus软件对第10层自振频率进行模拟，验证了所构建模型精度符合要求。通过Abaqus软件对单向振动作用、双向振动作用下构件时程反应进行分析；进一步地，基于损伤指数对剪力墙构件抗震性能进行评估。结果表明：所构建的剪力墙结构刚度比分布较为均衡；遭遇6度罕遇地震，只需对构件作稍微修复即可。

    Abstract：Having the common advantages of traditional masonry structure and reinforced concrete structure，reinforced block masonry shear wall structure has been widely used in the field of construction in our country. After building the finite element model of concrete，the tenth layer natural frequencies were simulated by Abaqus software，and the accuracy of the model was verified. Based on the Abaqus software，the time history response of the component is analyzed under the action of one-way and two-way vibration，and the seismic performance of the shear wall structure is evaluated by the damage index. The results show that the structural stiffness of the shear wall structure is distributed more balanced. When meet with 6 degree earthquake，slight repair on component is enough.
