中文摘要：

基于ABAQUS对砌体墙体建立了有限元模型，通过与试验墙体的对比，验证了所建数值分析模型的适用性；在此基础上，利用所建模型分别研究了构造柱、开洞情况、竖向压应力以及砂浆强度等因素对砌体墙体抗震性能的影响，并建立了2个层数不同的砌体结构算例，以研究结构高度对其抗震性能的影响．结果表明：构造柱能够提高砌体墙体的承载力和抗震性能；砌体墙体开洞会导致其承载力和抗震性能降低；砌体墙体的位移延性比随竖向压应力的增大而减小，但其承载力随竖向压应力的增大先增大后减小；砌体墙体的承载力和抗震性能随砂浆强度等级的提高而增大；砌体结构的结构高度越高，结构底层的受拉损伤越严重．

英文摘要：

The numerical analysis results from the finite element models through the software of ABAQUS were compared with the experimental results to verify the accuracy of finite element parameters. Tie columns, opening, vertical pressure and strength of mortar were considered to study the seismic performance of masonry walls by using the validated finite element models. Two masonry structure models with different layers were established to study the influence of structure height on the seismic performance. The results show that tie columns can improve the bearing capacity and seismic performance of the masonry wall, and the opening hole of the masonry wall reduces the bearing capacity and seismic performance of the masonry wall. The displacement ductility of the masonry wall decreases with the increase of vertical compressive stress. However, the bearing capacity of the masonry wall increases at first and then decreases with the increase of vertical compressive stress. The bearing capacity and seismic performance of the masonry wall increases with the increase of mortar strength grade, and the higher masonry structure results in more serious tensile damage.
