为了研究低剪跨比带约束拉杆的双钢板-混凝土组合剪力墙的抗震性能,对6个带约束拉杆的双钢板-混凝土组合剪力墙试件进行了滞回加载试验,研究了低剪跨比情况下包含不同参数的组合剪力墙的破坏模式、变形能力及耗能能力,得到了试件的滞回曲线、骨架曲线、承载力、位移延性系数、刚度退化曲线以及累计耗能曲线.然后,采用Open Sees程序对带约束拉杆的双钢板-混凝土组合剪力墙试件和普通钢筋混凝土剪力墙分别进行了数值模拟分析.研究结果表明:在低剪跨比情况下,带约束拉杆的双钢板-混凝土组合剪力墙的抗震性能良好;减小约束拉杆间距和端部增设型钢构件均可提高试件的承载力并改善其延性;与普通钢筋混凝土剪力墙相比,组合剪力墙的承载力和耗能能力显著提高.
In order to study the seismic behavior of double-steel-concrete composite shear walls with low-span and ratio-ratio tie rods, six double-plate-concrete composite shear wall specimens with restraining tie rods were subjected to a hysteretic loading test. The hysteresis curve, the skeleton curve, the bearing capacity, the displacement ductility coefficient, the stiffness degradation curve and the cumulative energy dissipation curve of the composite shear wall with different parameters are compared across the failure modes, deformability and energy dissipation capacity. Then the Open Sees program was used to simulate the double steel-concrete composite shear wall specimens with restraining tie rods and the ordinary reinforced concrete shear wall respectively.The results show that with low shear ratio, The anti-seismic performance of the double-steel-concrete composite shear wall of the tie rod is good; the reduction of the tie rod spacing and the increase of the steel members at the end can increase the bearing capacity of the specimen and improve the ductility; compared with the ordinary reinforced concrete shear wall, Shear wall capacity and energy consumption significantly improved.
