This paper studies on active control of structures subjected to near field earthquakes. In order to evaluation of effects of earthquakes with different frequencies three steel structures of 4, 8 and 15 floors with different natural period have been desined using ETABS software based on allowable stress method then opensees software have been used for three dimentional modeling of structures. Considering the impact and frequency content complexity of new field earthquakes, these structures subseetes to new field earthquakes. The different softwares have been used to verify of structures modelling. In order to evaluation of frequency content of earthquake, all of records scaled to 0.6 g then applied to structures. Different dynamic analysis conducted using eleven near field earthquake records and then the results compared to non-controled model to indicate the effect of active tendons.
