A Seismic Stability Evaluation of Buckling Restrained Braced Frames on West Coast [N8A]Buckling restrained braced frames (BRBF) have become popular seismic force resisting systems for low- and medium-rise buildings located in moderate and high seismic zones around the world. Using a 9-story steel-frame prototype, building performance based on code provisions from the U.S., Canada and Chile will be compared, particularly in terms of design seismic loads, drift limits, and requirements for P-delta effects. The three structures are considered to be located on the Pacific west coast on sites exposed to crustal and interface earthquakes. Seismic stability is examined through nonlinear response history analyses under representative site-specific earthquake record ensembles.
