Dynamic Analysis of Frame with Tuned Mass Damper by Considering Soil-Structure Interaction

One of the effective way that caused to decrease the response of structures is using of tuned mass damper.The dynamic behavior of these dampers is determined by natural frequency of structures and it is an efficient parameter for the response of structure. So the accurate determination of this frequency is veryimportant. In this paper the effect of soil- structure interaction with cones has been used in dynamic equation of structure with tuned mass damper. This paper presents that the response of structure with modeling of tow frames with different dynamic characteristic and tuned mass damper has been comparedby tow method with and without considering of soil-structure interaction. Also response of the frames hasbeen investigated with north-south component of horizontal ground acceleration recorded at the Elcentro during the earthquake of May 18, 1940. The comparison of results indicates that considering of soilstructure interaction in modeling has more efficiency in response of structure.
