Abstract: To understand mechanical characteristics and seismic behaviors of recycled concrete frame joints, the low cyclic loading tests were carried out on three frame interior joints made of recycled aggregate concrete with recycled coarse aggregate replacement rate 0%, 50% and 100% respectively. The mechanical characteristics, crack development, failure mode, hysteretic curve loops and ductility of joints with different recycled coarse aggregate replacement rates and same axial compression ratio are comparatively analyzed in this paper.
The result indicates that failure process of recycled concrete frame joints is similar to that of ordinary concrete frame joints, and the ductility and energy dissipation ability of the former is slightly variant to those of the latter. The frame joints made of recycled aggregate concrete with suitable replacement rate can be applied in building structure, but the frame joints construction must be strengthened.
