| Abstract: | Buckling-restrained brace (BRB), with enhanced lateral stiffness and higher earthquake energy dissipation capacity, it can be used in seismic mitigation and retrofitting of structure. Taking an engineering case as an example, this paper describes the process and merit of the BRB technology. Since this technology has been popularly applied in foreign countries, we put forward some suggestions for making good use of this technology in China. |
