This work aimed to identify the seismic behavior of buckling restrained braced frames (BRBFs). A six-story frame with buckling restrained braces was analyzed at different hazard levels. After the discussion of some aspects of BRBs, the results of detailed nonlinear dynamic analyses are examined to characterize the seismic behavior of the model building. Also the effect of near-field ground motions on the behavior of the model was studied. The results indicate that BRBFs behave quite well under seismic loads. However, there are some concerns about the performance of this system under more frequent lower intensity ground motions.
