With a good hysteretic behavior, the BRB is a kind of element which could serve as both lateral force resisting and energy dissipating component. With the introduction of several projects, the main technologies were studied such as design, construction and acceptance criteria of the application of BRB in strengthening project, and the advantage of applying this technology in the related projects was also elaborated.
Keywords: buckling restrained brace; strengthening project; construction method; acceptance criteria
