000020119 520__ $$2eng$$aBuckling-restrained braces (BRBs), developed in the late 1980’s in Japan, are now widely used as ductile seismic-resistant and energy dissipating structural members in seismic regions such as the US, Taiwan, China and NZ. They are expected to exhibit stable hysteresis when subjected to in-plane cyclic axial loading, as described in the seismic provisions of AIJ 2009 and AISC 341. However, several recent studies have highlighted the risk of global BRB buckling induced by plastic hinging at the restrainer end prior to core yielding and subsequent connection instability. Various equations evaluating this stability limit have been proposed, but the relationship among these criteria is not clear. This paper reviews and compares these equations, introduces a unified concept and proposes a simplified approach for practical design.
