     the interest in the application of multiple tuned mass dampers (mtmd) as a useful passive control method is pervasive throughout the structural engineering over the last decades. tuning the dampers to the fundamental period of the structure can improve the seismic behavior of the structure due to energy absorption enhancement of the system. in seismic retrofit, the performance levels of the structure in the different levels of earthquake are determined based on some parameters such as the relative displacement of the roof or the plastic hinges rotation capacity of the structural system. since attaching mtmd to the structure can improve these seismic responses of the structure significantly, we propose an optimum mtmd to improve the performance levels of the structure. the obtained results from nonlinear dynamic time history analyses show that attaching mtmd to the structure can be a powerful method for the structurally retrofitting.
