The buckling-restrained braces (BRB) or energy dissipated connectors (EDC) can obviously improve the seismic performance of engineering structures, while their behavior was often limited by the premature failure of the gusset connection or the frame joint. In this study, a novel dry-connected BRB precast concrete frame (BRB-PCF) with EDC was proposed, which featured a predetermined yield sequence: the weakened section of the BRB core plate, the unweakened section of the BRB core plate, the EDC, and the steel bars in the PC beam end. Cyclic tests were conducted on one BRB-PCF, one bare PCF and one repaired PCF to comprehensively investigate the seismic performance and the repairability of the proposed structure. The failure process, hysteresis curves, energy dissipation capacity, strength, and stiffness were studied. Test results showed that the BRB-PCF successfully achieved the predetermined yield mechanism and failed at the PC beam end, while the damage was concentrated at the EDC for the bare PCF, both of them exhibited excellent seismic resistance. The strength, initial stiffness, and cumulative energy of BRB-PCF were 2.1, 5.1, and 3.2 times that of the bare PCF, respectively, indicating the increased bearing capacity, stiffness, and energy dissipated capacity due to the presence of the BRB. Additionally, the BRB kept a high energy dissipation efficiency from 0.2 % to 3.0 % drift ratio. Finally, the working mechanism was elaborately analyzed and discussed. The added strength and stiffness were calculated, and the results were in good agreement with the experimental results.
