【摘要】：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.
[Abstract]:In order to study the seismic behavior of double steel plate concrete composite shear wall with low span ratio constraint bar, six specimens of double steel plate concrete composite shear wall with constraint bar were tested by hysteretic cyclic loading. The failure mode, deformation capacity and energy dissipation capacity of composite shear wall with different parameters are studied in the case of low shear span ratio. The hysteretic curve, skeleton curve, bearing capacity and displacement ductility coefficient of the specimen are obtained. Stiffness degradation curve and cumulative energy dissipation curve. Then, the Open Sees program is used to simulate the specimens of double-plate-concrete composite shear wall with constraint bar and the normal reinforced concrete shear wall respectively. The results show that under the condition of low shear span ratio, the aseismic performance of double-plate-concrete composite shear wall with restrained strands is good, the bearing capacity and ductility of specimens can be improved by reducing the spacing of restrained strands and adding steel members at the end. Compared with ordinary reinforced concrete shear wall, the bearing capacity and energy dissipation capacity of composite shear wall are improved significantly.
