For the past four decades, researchers have worked upon and developed a bracing system. called the buckling restrained brace (BRB) for frame braced structures. This system counteracts compression from buckling during strong earthquakes. The system has the advantages of a common brace and damper, providing lateral stiffness to the structure under frequent earthquakes. Seismic energy can be dissipated by the steel core yield, under both rarely expected and moderate earthquakes. This paper is devoted to the concept of BRB, its components, characteristics, and its current deficiencies. It also discusses the current limitations and estimates the developing trend of this technique. It has a certain reference value for in-depth studies on BRB system.
