Buckling‐restrained braces (BRBs) are a relatively recent development in the field of seismic‐resistant steel structures. Their distinctive feature is the non‐buckling behaviour typically achieved by encasing a steel core in a concrete‐filled tube, but alternatives have been proposed. Restraining the brace from buckling enhances ductility significantly and allows a symmetric response under tension or compression forces. The design of BRB frames must consider a number of specific issues that are currently not covered by European standards and regulations. This paper presents a brief summary of the most recent research results and attempts to summarize the basic design issues as they emerge from both research and the codification rules of non‐European Countries. Conclusions are drawn regarding future research required to address the development of design rules in Europe, too.
