中文摘要：
基于有限元软件ABAQUS对T型截面带翼缘剪力墙在双轴反复荷载作用下的抗震性能进行数值模拟,通过与已有实验结果的对比,验证了有限元模型的有效性.通过对研究模型的模拟,分析比较了双轴加载较单轴荷载作用下各方向性能的差异,对比了不同双向加载路径对其抗震性能影响.结果表明：除x轴反向加载（腹板端部受压时）外,其余方向双轴加载较单轴均表现出明显的双轴耦合效应,承载力降低,强度和刚度退化加剧,延性减弱;其中＂8字形＂加载路径影响最大.
英文摘要：
Seismic behavior of T-shaped cross-section shear walls with flange under biaxial repeated loads was simulated based on the finite element software ABAQUS respectively,and the calculated results were compared with those of the experiment to ensure the effectiveness of the simulation model.With the simulations of the model researched in this topic,the performance differences between biaxial loading and uniaxial loading were analysed in both direction,the influence of different biaxial loading paths on seismic performance was compared.Compared with uniaxial loading,the results show that biaxial coupling effect is obvious,meanwhile,the bearing capacity decreases,the strength and stiffness degradation becomes worse and displacement ductility reduces except for the x reverse loading（when the web end is in compression）.The influence of loading path ＂8＂ is largest among them.
