Current trends in construction industry demands taller and lighter structures, which are also more flexible and having quite low damping value. This increases failure possibilities and also problems from serviceability point of view. Now-a-days several techniques are available to minimize the vibration of the structure. Out of the several techniques available for vibration control, concept of using TMD is a new one. An earthquake directly affects a structure by increasing the energy within the structural system. A significant portion of this energy can be dissipated and/or reflected through the introduction of a passive, active, or semi-active control system. If certain performance criteria are established which require continuous reconfiguration of the structural system, either an active or semi-active control system will generally be required. In the case of semi-active control systems, the control forces are developed by the motion of the structure itself through appropriate adjustment of the stiffness and/or damping characteristics of semi-active control devices. Passive control systems do not require any kind of external energy. Tuned mass damper is a structure, connected to the main structure by means of springs and the parameters of TMD are tuned to that of main structure such that the dynamic response of main structure during Earthquake is reduced. Since every building necessarily needs water tank, usage of water tank as vibration control device is advantageous. Two buildings, one of which is 5 storied and the other is 10 storied are analyzed using time history analysis in SAP 2000. Behavior of structure subjected to El-Centro earthquake data, Bhuj earthquake data, Kobe earthquake data is studied. For each case, analysis is done for mass ratios varying from 5% to 25% for every 5% interval. Column height on which water tank is placed is also changed for 1m, 2m, 3m, 3.5m and its behavior is observed. From the study it was found that, for both 5 storied and 10 storied structures, placing water tank on 3m column height and mass ratio 20% gives optimum response reduction.
