Overstrength Factors of Buckling Restrained Braced Frames

Abstract

In this study the overstrength factors of medium to low-rise bucking restrained braced frames (BRBF) were evaluated. Various design variables, such as number of stories, span length, yield strength of the brace, level of earthquake load, and the response modification factors. The overstrength factors were obtained using the nonlinear static analysis following the procedure proposed by ATC-19. According to the analysis results, the overstrength factors obtained from this study were generally larger than those proposed in `AISC/SEAOC Recommended Provisions for BRBF`.
