While some tests indicate excellent performance of BRBs, studies in recent years have demonstrated premature failure mechanisms which can occur at loads/displacements significantly less than those anticipated by conventional design checks. This paper lists published BRB and BRB system failures that have occurred around the world during testing. These have included sway buckling of the gusset, plastic hinging at the restrainer end, gusset weld fractures, local buckling and fracture of the adjacent framing members, and restrainer wall bulging. Simple theory is used to explain why each of the failures occurred. This information is used to better inform the design process. As a result of the study, it is shown that some commonly used design procedures are not appropriate. As an example, the use of an effective length factor k e < 1 for the gusset plate that can fail by sway may be non-conservative. Also, state-of-the-art design methods to obtain reliable BRB system performance under expected deformations are provided.
