摘要: 通过对6个T形和6个L形截面短肢剪力墙试件进行拟静力试验，研究短肢剪力墙的基本受力性能和破坏模式。应用有限元软件ANSYS对试件的非线性力学性能进行分析和改进。计算和试验所得的荷载-位移骨架曲线比较接近，证明了模型的合理性。通过改变参数，分析了参数变化对其力学性能的影响；针对T形截面短肢剪力墙抗震薄弱部位，对其进行了力学性能改进分析。结果表明，通过在其腹板边缘约束构件内加入钢管，可以明显提高腹板的抗拉、压能力，使抗震性能得到了较好的改善。Abstract: Cyclic loading test of six T-shaped and six L-shaped short pier shear wall specimens were conducted to investigate the fundamental mechanical properties and failure mode.Nonlinear mechanical properties of specimens were analyzed by software ANSYS.Finite element model was reasonably proved by the satisfactory agreement between analytical and test results.The effect of parameter variation on mechanical properties of specimens was investigated by changing parameter.Nonlinear finite element analysis showed that seismic performance of short pier shear wall was greatly improved by adding steel tubes in the confined boundary elements.
