Abstract: This research covers a comparison between different configurations for the application of Buckling Restricted Brace (BRB) through the dynamic analysis of an irregular building that does not comply with the maximum drifts in one of its directions and is reinforced with the different configurations. Unlike other research, the factors considered take into account the seismic conditions of Peru and are evaluated under the national regulation E.030 2018. In addition, it seeks to promote research into unconventional structural reinforcement methods in Latin America. The reinforcement with BRB was achieved with the four distributions analyzed: BRB V, Inverted BRB V, BRB X and 2-story BRB X. These configurations were applied to the weakest frames of a building with a basement, 5 floors and a roof terrace. In that sense, the configuration that had better performance was 2-story BRB X, with a reduction of the maximum inelastic story drifts of 28.71%.

Keywords: Buckling restrained brace, Dynamic analysis, Structural reinforcement, Latin America, Inelastic drifts.
