WebFeb 4, 2024 · Buckling-restrained braces (BRBs) are widely used to improve the seismic performance of buildings. This paper aims to introduce BRBs to suspension bridges and assess the seismic performance of bridges with BRBs. Taking the Dadu River Bridge as a case study, an FEA model of the bridge is established, and different seismic measures … WebA 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 ...
