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OpenSees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 behaviors of low shear-span ratio composite concrete and double steel plate shear walls with binding bars,hysteretic loading tests were conducted on six specimen of composite concrete and double steel plate shear walls with binding bars. The failure modes,deformation performance and energy dissipation capacity of low shear-span ratio shear walls with different parameters were studied.The hysteretic loops,skeleton curves,bearing capacity,displacement ductility coefficients, stiffness degradation curves and accumulated energy dissipation curves were obtained. Then, numerical simulation analyses were conducted on the test specimen and the traditional reinforced concrete shear wall by the software OpenSees. The results indicate that the low shear-span ratio composite concrete and double steel plate shear wall with binding bars exhibit good seismic behavior. The bearing capacity and the ductility can be enhanced by decreasing the binding bar spacing and setting of the end steel shape.Compared with the traditional reinforced concrete shear wall, the bearing capacity and energy dissipation capacity of the composite shear walls are greatly improved.
