The most modern control techniques to improve the structural behavior of structures against unconventional forces of wind and earthquake. In this regard, researchers using innovative tools such as tund mass damper (TMD) to reduce seismic vibrations. This paper examines the effect of the position and the percentage by mass damper TMD plan on seismic performance of concrete structures. For this purpose, a concrete structures eighteen floor, are selected. The TMD are uniformly distributed along the height of the structural models. Nonlinear dynamic time history analyses are used to determine the add TMD related response reduction. The results show an reduction in the dynamic response, by increasing damping ratios of structural systems caused by add TMD. Therefore, such systems can be used to retrofit buldings and improve their behavior under earthquake used.
