Today, types of seismic isolators are used, in order to control the vibration of a structure against earthquake forces, as depreciated energy systems, to concentrating inelastic deformation, when the earthquake will be accurred, the work of restoration and rehabilitation of structures will be facilitated, in these systems. On the other hand, use of toned mass dampers adjusted, can increase the inherent damping of the structure, and decreased seismic response. In fact, the methods mentioned above, as passive control techniques are used to improve the structural response. Therefore, for checking the result of using these methods on the performance of concrete structures, a concrete building with 15 floors is modeled, in three-dimensional, and discrete models, the separating rubber - Lead, separating Pendulum isolator, the single toned mass in amount of 6 percent by weight of the first mode, at the level of the roof, and two toned masses , each with a rate of 3 percent, at the level of the roof, and at the lower level of roof, is used to evaluate the structural response. The results show that all methods can reduce the roof displacement. Comparison of all results is presented in the article
