It consists of a slender steel core, a concrete casing designed to continuously support the core and prevent buckling under axial … See more The concept of BRBs was developed in Japan by Nippon Steel at the end of the 1980s and was known by its trademark name of Unbonded Brace. It was first installed in the United States in 1999, in the Plant & … See more Three major components of a BRB that can be distinguished are its steel core, its bond-preventing layer, and its casing. The steel core is designed to resist the full axial force developed in the bracing. Its cross-sectional area can be significantly lower than that of … See more The purpose of buckling-restrained braces is to dissipate lateral forces from columns and beams. Therefore, the connection of the braces to beams and columns can greatly affect the … See more Buckling restrained braces rely on the ductility of the steel core to dissipate seismic energy. As the steel core yields, the material work-hardens and becomes stiffer. This work … See more Because BRBs achieve a high level of ductility and stable, repeatable hysteresis loops, BRBs can absorb significant amount of energy during cyclic loadings, such as an earthquake event.
