摘要:

In order to investigate the aseismic performance of the mid-rise recycled concrete shear wall with the different percent of fine aggregate replacement, reinforcement ratio and axial compression ratio, a low-frequency quasi-static cyclic loading experimental study on seven mid-rise shear walls with a shear-span ratio of 1.5 was carried out. Based upon the experimental study, the load-carrying capacity, ductility, stiffness, hysteretic behavior, energy dissipation and failure phenomena of each shear wall were analyzed. The experiments indicate that the more of the fine aggregate replacement, the poorer the aseismic performance of a recycled concrete shear wall, and the aseismic performance of a recycled aggregate concrete shear wall could be greatly improved by increasing the reinforcement ratio. With the increasing of the axial force ratio, the load-carrying capacity of the shear wall is increased but the ductility is decreased. At some conditions, the recycled aggregate concrete shear wall is able to satisfy the structure aseismic design requirement.
