| Abstract | ||||
| The buckling-restrained brace (BRB) is a development of conventional braces that not only increases the compressive resistance of the brace but also improves seismic energy dissipation. The fundamental difference between the BRB and common types of braces is that in the BRB, buckling is prevented by a restrained mechanism, which leads to a reduction in the cross-sectional area of the inner core. This results in plastic deformations of the inner core of the BRB without buckling, which causes seismic energy dissipation. Due to the superiority of the BRB over other types of dispersing devices, many studies have been conducted to improve its performance. In this research, the results of some researches over the past few decades were presented to clarify the beginning, development, types, design strategy, and applications of BRBs. Numerous studies have presented numerous proposals for the development of BRBs to increase their efficiency and decrease their costs. The scope of these studies was the development of the basic parts (core, restrained mechanism, and connections) of BRBS. | ||||
