A set of structures with different number of stories and dynamic characteristics, including structures with stiffness and mass irregularities, were used in the analysis. The effects of each parameter on different structures were quantified and compared to the responses of structures without MTMD, using several ground motions. The performance was measured in terms of reductions of maximum displacement and drift of structures. The results show that seismic responses of structures can be improved using MTMD with optimum parameters, although the optimum values may vary according to structural and ground motion properties. The structural performance tends to improve as the mass ratio of MTMD increases. However, the effect of mass ratio also varies for different structures and ground motions. From location and distribution aspect, in general, adding MTMD to the structural system reduces structural responses regardless of the placement. However, it seems that MTMD located at the top story generates better performance for structures with dominant first mode, even if the structures have variations of story masses and stiffnesses along their heights. The result also shows that adding MTMD to the structural system somewhat reduces the drift demand and linearizes the drift pattern, thus easing the drift demand for the lower floors.
