Buckling-restrained braces (BRBs) are able to dissipate a large amount of energy due to their ductile capacity compared with conventional braces. And also their symmetrical and excellent hysteretic behavior helps predicting of their behavior. In this paper a conventional moment resist-chevron brace dual system and a moment resist-BRB dual system is modeled and subjected to a cyclic load up to 6% drift angle ratio using ABAQUS. Energy dissipation and ductility factor of both systems had calculated and compared.
