Abstract:
A low-frequency quasi-static cyclic loading experimental study on seismic performance of the recycled aggregate concrete (RAC) shear walls were systematically carried out The load-carrying capacity stiffness, degradation process of stiffness, ductility hysteretic property, energy dissipation and damage characteristics of the specimens with RAC and the specimens with the usual concrete in different shear-span ratio were compared The influence of the seismic performance of specimens with different shear-span ratio, different amount of coarse recycled aggregate replacement different reinforcement percentage, different axial-force ratio, different reinforcement design and construction measures were studied Experimental study indicated that the load-carrying capacity and ductility of the specimens with RAC showed a little lower compared to the corresponding specimens The latter stiffness of the two kinds of specimens tended to accordance even though the initial stiffness of those with RAC was lower because of their different elastic modulus It can meet the structure requirements that the RAC shear walls are applied in the multi-story buildings in seismic zones belong to fortification intensity 8 or lower, or the upper part of tall buildings under lower force through reasonable design
