Abstract

Buckling-restrained braces (BRBs) are widely used as highly ductile seismic devices, with the first building using BRBs completed in 1989 in Tokyo, and thousands more now in Japan, USA, Taiwan, China, New Zealand and other countries.

Although design codes of several countries specify BRB performance criteria, detailed design provisions are not necessarily provided, as BRBs are typically treated as a manufactured device. This paper briefly reviews the early history of BRB research and offers state-of-the-art views on the design criteria required to obtain stable and reliable performance. Representative project examples and up-to-date studies relevant to tall buildings are summarized.
