Reinforcement of structures with concrete moment frame system by submitting metal damper with optimal cross section has been done in the present study. To investigate the effect of damping on the behavior of the structure, the structural system with the proposed damper was compared with three types of bearing systems of different structures of concrete moment frame, concrete shear wall and bracing with different number of floors 8, 14 and 20. In this study, 4 groups of concrete structures were studied and compared in terms of lateral bearing system, including medium concrete moment frame with behavior coefficient (R = 5), medium concrete moment frame with shear wall with medium ductility, concrete moment frame with Medium ductility with EBF steel brace and Medium ductility concrete moment frame with EBF steel brace Equipped with yielding metal damper. The studied structures have building frames with dimensions of 25 x 25 meters, which are modeled on 8th, 14th and 20th floors. Each dimension of the structure in the plan has 5 openings with lengths of meters. In modeling structures with dampers, four types of dampers modeled with 4, 6, 8 and 10 flowing plates in the damper have been used. By comparing them, it has been determined that the damping with 10 flowing plates has better performance and the results of that structure in Comparison with other systems was used. In 8-story models, the maximum final displacement in the brace was 17% higher than in the damper. The 8-story structure with dampers not only withstood the highest shear but also had the best performance compared to other systems. The results show that in structures with a low number of floors, the use of the system with the proposed damper is more appropriate and in medium structures, the shear wall system has a better performance.
