Recently, as the number of earthquakes has increased, the building structure standard has been revised in 2016. In order to minimize earthquake damage, steel frame is used as the most economical and efficient lateral resistance system. Also, when the steel braces are subject to Compressive load, which causes unstable behavior of the structure. In order to verify the compressive behavior of the reinforced Braces, structural performance tests were conducted with variables of slenderness ratio and the amount of reinforcement. This study investigates the structural performance of existing double - angle steel braces by reinforcing them with non- welded/assembled light-weight steel frames and proposes a suitable reinforced section.
