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。
The pseudo-static tests of six T-shaped and six L-shaped short-leg shear wall specimens are carried out to study the basic mechanical properties and failure modes of the short-leg shear wall. The finite element software ANSYS was used to analyze and improve the nonlinear mechanical properties of the specimens. The calculated “load - displacement ” skeleton curves obtained by experiments are close to each other, which proves the rationality of the model. By changing the parameters, the influence of the parameter changes on the mechanical properties was analyzed. Aiming at the weak earthquake-resistant part of the short-limb shear wall with T-shaped cross-section, the mechanical properties were improved. The results show that the tensile and compressive strength of the web can be obviously improved by adding the steel pipe into the restraining members on the edge of the web, so that the seismic performance is improved well.
