Steel bracing is an effective and economical retrofitting technique for upgrading deficient reinforcedconcrete moment resisting frames typically found in the developing countries. Steel bracing not only increases thestrength, stiffness and energy dissipation capacity of the system but also provide sufficient ductility under an earthquakeevent. This paper numerically investigates the seismic performance of eccentric steel braces connected diagonally toreinforced concrete beam at a distance of Lbeam/6 from the face of the column. Static time history analysis was performedon a single story reinforced concrete bare frame and eccentric steel brace retrofitted frame using a finite elementprogram. Results showed that frame retrofitted with eccentric steel brace changes the lateral load transfer path andreduces the demands on the most crucial zone beam-column joint and as a result increases the strength, stiffness andenergy dissipation capacity of the frame as opposed to bare frame
