In the Modern World and development of construction technology an‎d the increase in construction costs increasingly require the retrofitting of existing structures to be felt. There are many ways for seismic retrofitting of existing concrete structures designed and implemented and examined and tested by professionals around the world. Among the available methods of enforcement methods steel brace in concrete structures is of special interest. In this study, the dynamic spectral analysis performed on the five-story reinforced concrete structures that are seismic retrofitting by the steel brace. Location steel brace structures in height, was analyzed and the best way to reach the openings bracing to achieve maximum efficiency and minimum seismic relative displacement is determined.
