Dynamic response of a base isolated multi-storey plane frame structure with Multiple Tuned Mass Dampers (MTMD) subjected to harmonic ground excitation and Mexico earthquake excitations are studied. A four-storey plane frame structure having three degrees of freedom (two translations along x, y -axes and one rotation about z- axis) at each node, with MTMD on its base is considered for study. Comparison of response is made in terms of displacements and forces in order to investigate the effectiveness of the MTMD. The response of base isolated structure with MTMD is found to be less in comparison to the corresponding response without MTMD, implying that the MTMD is effective in reducing forces and displacements of the base isolated structure.
