The construction speed and quality of precast frame structures are greatly influenced by weld, tie, prestress, cast concrete requirements, etc. on site. To address these challenges, a precast beam-column joint connected by double grouted sleeves is proposed. This paper presents an investigation on seismic behaviour of the joint subjected to static and cyclic loadings. In total, six precast specimens with different assembly lengths, transition bar diameters and types of grouted sleeve and one cast-in-place control specimen were tested. Results show that the double grouted sleeve splices in joints perform well. The initial stiffness of prefabricated specimens is larger than that of the control specimen and the load bearing capacity of the prefabricated specimens is similar to that of the control specimen. As the transition rebar diameter increases from 16 mm to 18 mm, the energy dissipation ability of the prefabricated specimens is increased by 64.8% but is approximately 41% lower than that of the control specimen due to their relatively lower deformation capacity. Threads in the grouted sleeve have a negative impact on the deformation and energy dissipation abilities of the joints. The method for cast-in-situ joint is adequate for predicting the flexural capacity of precast joint connected by double grouted sleeves.
