Nowadays, various types of seismic isolators are used as energy-dissipating systems to control structural vibrations against earthquake forces, so that inelastic deformations during earthquakes are concentrated in these systems and the repair and improvement of structures is also facilitated. On the other hand, the use of tuned mass dampers can increase the inherent damping of the structure and reduce the seismic response and damage in structure and improved the behavior of structure . In fact, the methods mentioned above are used as passive control methods to improve the response of the structure and the behavior of structure.Therefore, to examine the results of using these methods on the performance of concrete structures, a concrete building with 15 floors has been modeled, and in separate models, a rubber-lead isolator, a friction pendulum isolator, a single tuned mass of 6% by weight of the first mode at the roof level, and two tuned masses of 3% each at the roof level and the lower roof level have been used to examine the response of the structure. The results show that all methods have reduced the roof displacement. A complete review and comparison of the behavior results of structure ,is presented in the text
