Seismic Response of Buckling Restrained Braced Frames under Near Fault Ground Motions

Z. Baghbanijavid, A. Jalali and Y. Yasrebinia

Abstract:
Buckling Restrained Braces (BRBs) yield in tension and compression, exhibit stable and predictable hysteretic behavior, provide significant energy dissipation capacity and ductility and are an attractive alternative to conventional steel braces. Present study conducts numerical simulations of buckling restrained braced frames responses using a suite of near-fault ground motion records, to evaluate the seismic responses of Buckling Restrained Braced Frames (BRBFs) in near-fault areas. In order to evaluate responses, 4 buildings with buckling restrained braced frames were modeled in nonlinear analysis program. Comparing the results of numerical model with experimental results showed that the numerical model of BRBF has been accurate to simulation. To evaluate the seismic response of buildings, a 4 story model analyzed with selected records; this process repeated for buildings with 3, 9 and 12 story. The analysis results showed that the performance of the BRBFs was acceptable but the residual story drifts were very high and this affects the performance of the non-structural systems in BRBFs in near-fault areas. Some of the provisions of AISC were not conservative and the responses of the frames under near-fault ground motion were not mode-based, it was wave-based.
