Unbonded Brace, Buckling-Restraind Brace, Steel Frame Design, BRB, BRBF

Unboned Brace started the building-restrained brace (BRB) revolution in the U.S. and is the brace of choice for owners, architects, engineers and fabricators seeking superior seismic performance.

It is the most rigorously reviewed and approved BRB system, accepted by more regulatory agencies than any other including the State of California Office of Statewide Health and Planning and Development (OSHPD), the State of California Division of the State Architect (DSA), as well as the U.S. federal government, county governments and numerous local jurisdictions.

Over 25 years of quality and innovation

Unbonded Brace's superior hysteretic performance results from years of research and development, more than 15 full-scale testing programs in the U.S., and hundreds of braces tested in the U.S., Japan and around the world.
