摘要:
针对T 形截面带翼缘剪力墙在单、双向反复荷载作用下的抗震性能进行了数值模拟，通过与试验结果比对，验证了
有限元模型的适用性；进一步研究了双向荷载作用下双向加载路径、轴压比、边缘构件箍筋对T 形截面剪力墙抗震性能的
影响．结果表明：除个别情况外，双向加载较单向加载均表现出明显的双向耦合效应，承载力和延性降低，强度和刚度退化
加剧，且加载路径对抗震性能影响显著；随着轴压比的增大，在两个加载方向上的屈服荷载和屈服位移增大，强度和刚度退
化加剧，位移延性降低，除腹板端部受压外，其余方向的峰值荷载均有提高；减小约束边缘构件箍筋间距使得各项性能指标
均有提高，但在翼缘受压方向影响较小．
Abstract:
Seismic behavior of T-shaped shear wall with flange under the unilateral and bidirectional cyclic loading was simulated using the finite element (FE) method in this study. The performance and validation of the proposed FE model was firstly verified by comparison with the experimental results. The effects of the bidirectional loading path, the axial compression ratio and the stirrups in the boundary elements on the seismic behavior of the T-shaped shear walls under the bidirectional load were then investiagted. Compared with the results from the unilateral load, the bidirectional load leads to an obvious bidirectional coupling effects,and they decrease in the bearing capacity and the ductility, and dramatical degradation in the strength and stiffness. It is also shown that the loading path has the critical effects on the seismic behavior of the T-shaped shear walls. In addition, the greater axial compression ratio results in the increases of the yield strength and yield displacement, the development of the strength and stiffness degradation, as well as the reduction of the displacement ductility in both loading directions. Meanwhile, the peak load is improved due to the greater axial compression ratio except when the web end is under compression. Shortening the stirrup spacing of the confined boundary elements can make a positive contribution to the behaviour of the T shaped shear walls, which affect less when the flange is under compression
