In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures incorporating these dampers. Therefore, the metallic dampers and the behavior of concrete structures having these dampers are studied first. Afterwards, a typical metallic damper is used in four different types of concrete structure. The required dampers are designed and nonlinear earthquake analysis is applied to investigate the behavior of the structures. Finally, the buildings are subjected to various earthquakes to generalize the results. The results show that the incorporation of the metallic dampers significantly decreases the relative and absolute drift, the structure and the stories damage indices and, finally, the number of plastic hinges. Furthermore, the hysteretic energy dissipation demand also decreases in structural components. Despite the reduction in the inner forces of structural components, story shear forces slightly increase due to increase of lateral stiffness, but much of these forces will concentrate in dampers. Moreover, the combination of moment resisting frame, shear wall, and metallic dampers are studied. The results show a similar trend in the stated parameters- especially the drift and the hysteresis energy dissipation demand.
