 Tests have demonstrated BRBF systems are highly effective for energy dissipation, while being vulnerable to large deformations and story drift.A buckling-restrained brace (BRB) consists of a steel core surrounded by a hollow steel section, coated with a low-friction material, and then grouted with a specialized mortar.The encasing and mortar prohibit the steel core from buckling when in compression, while the coating prevents axial load from being transferred to the encasement, thus preventing strength loss and allowing for better and more symmetric cyclic performance.
