| Abstract: | This paper introduces the research results of buckling-restrained braces (BRBs) in recent years in China and focuses on the research status of BRB members (core element, restraint mechanism, cohesionless layer), overall seismic performance, and design methods. Based on the review, the following is concluded: the BRB has a good development potential because of its good energy-dissipation performance; the application scope of the BRB is expanding; the structural forms are becoming more diversified; and the design methods are constantly being optimized. |
