Experimental Study on Seismic Performance of Prefabricated High-strength Recycled Concrete Shear Walls
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.
