WebRestrained warping is important for the torsion deformation and axial stresses of thin-wall open sections. However, this phenomenon is not included in commonly used frame analysis programs. This pape A buckling-restrained brace (BRB) is a structural brace in a building, designed to allow the building to withstand cyclical lateral loadings, typically earthquake-induced loading. 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 … See more The purpose of buckling-restrained braces is to dissipate lateral forces from columns and beams. Therefore, the connection of the braces to … 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. Preventing buckling leads to similar strength and ductile … See more Comparative studies, as well as completed construction projects, confirm the advantages of buckling-restrained braced frame (BRBF) … See more • Intermountain Medical Center • Levi's Stadium - home of the San Francisco 49ers See more ground storage reservoir
