Owing to the stable hysteresis behavior and favorable costs, the buckling-restrained brace (BRB) is a high-performance damper in seismic areas to protect the building structures from severe damage, especially for steel frames. However, the combination of BRBs and reinforced concrete (RC) structures is complicated, due to the material difference between BRBs and the RC. This study briefly offers state-of-the-art views on the key issues of the combination of BRBs in RC frames (RCFs), such as BRB units, BRB-to-frame connections, seismic design approaches, and performance evaluation procedures. Despite excellent seismic behaviors can be ensured in many BRBs and gusset plates, more high-resilience components require further research. The BBR-to-frame interaction behavior, story shear force distribution relationship, strength and stiffness requirement, and BRB fatigue damage should be taken into account in the design of BRB-RCF systems. This paper aims to provide some recommendations for the development and future prospects of BRBs in RCFs.
