摘要:

To know the seismic performance of the low-rise recycled concrete shear wall with different percent of recycled coarse aggregate and recycled fine aggregate, a low-frequency quasi-static cyclic loading experiment on low-rise shear walls with a shear-span ratio of 1.0 was carried out. They are one usual concrete shear wall, three recycled concrete shear walls, and one recycled concrete shear wall with concealed bracing. Based on the experimental study, the load-carrying capacity, stiffness, ductility, hysteretic behavior, energy dissipation, and failure phenomena of each shear wall are analyzed, and the bearing capacity is calculated theoretically. Results indicate that the low-rise shear walls with recycled coarse aggregate show poorer seismic performance than the common wall, and the recycled coarse aggregate replacement has little influence on the seismic performance of the shear wall; however the recycled fine aggregate replacement has a little larger influence. The recycled concrete shear wall with concealed bracing shows much better seismic performance.
