This paper presents analytical investigation carried out to study the feasibility of implementing water tank as passive TMD using ANSYS. Two multi-storey concrete structures, three and five storey were taken for the study. The water tank was placed at the roof. The mass and frequency of the tank including its water, walls, roof, beams and columns were tuned to the optimized values. The behavior of the tank subjected to four earthquake data, namely, E1-centro, Hachinohe, Kobe and Northridge was studied under five conditions, namely tank empty, 1/4th water, 1/2th water, 3/4th water and full tank. The results show if the tank is tuned properly it can reduce the peak response of structures subjected to seismic forces.
