摘要

Buckling-restrained braced frames are a new steel seismic-load-resisting system that has found usernin California and the West because of its efficiency and its promise of seismic performance far superior to that ofrnconventional braced frames. The system is not yet addressed in the AISC Seismic Provisions, but nevertheless a setrnof design provisions has been developed by AISC in conjunction with the Structural Engineer’s Association ofrnCalifornia. The paper addresses the design and specification aspects of using this new system. The presentationrnincludes a design example of a seven-story buckling-restrained braced-frame building, which will be available in arnSteel Tips publication this year. A discussion of the appropriate analytical methodologies, as well as the requiredrntesting of the buckling-restrained braces, is also addressed. The specification of braces from currently activernmanufacturers is addressed. Finally, special considerations for enhanced seismic performance goals are discussed.
