Recommended Procedures for Buckling- Restrained Brace Frames

This paper contains a document that has been developed to serve as a supplement to existing building codes in order to give guidance to design engineers wishing to employ buckling-restrained braced frames on projects in the United States, as well as to the building officials to whom such designs are submitted. It is expected that the Recommended Provisions for Buckling-Restrained Braced Frames will be included in the 2005 edition of the AISC Seismic Provisions for Structural Steel Buildings. All of the provisions presented are currently under review in the draft of the 2005 Seismic Provisions. The provisions, as they are presented, are suitable for use with the 2002 Seismic Provisions, and include references to other sections of those provisions throughout. Therefore, consistent with the 2002 Seismic Provisions, LRFD format is used.
