摘要
文中在低周反复加载作用下,测试装配式高强再生混凝土剪力墙滞回性能、刚度退化、耗能能力以及残余变形等特性,分析墙体材料对再生混凝土剪力墙抗震性能的影响.结果表明,掺杂1.0%钢纤维的再生混凝土剪力墙的抗震性能最佳.与普通混凝土剪力墙相比,钢纤维再生混凝土剪力墙的极限承载力增加19.33%,普通混凝土剪力墙残余变形为2.06%,钢纤维再生混凝土剪力墙残余变形为0.85%,表明其抗变形能力同样得到增强.
Abstract
In order to respond to the call of green and sustainable development of the construction industry,this paper analyzes the seismic per-formance of prefabricated high-strength recycled concrete shear walls by testing hysteretic properties,stiffness degradation,energy dissipation capacity and residual deformation under low-cycle repeated loading.The results show that the recycled concrete shear wall doped with 1.0%steel fiber has the best seismic performance.Compared with ordinary concrete shear wall,the ultimate bearing capacity of steel fiber reinforced concrete shear wall is increased by 19.33%,the residual deformation of ordinary concrete shear wall is 2.06%,and the residual deformation of steel fiber reinforced concrete shear wall is 0.85%,indicating that its deformation resistance is also enhanced.
