WATER TANK AS A TUNED MASS DAMPER

Water tanks are integral part of all buildings and they impart large dead load on the structure. This additional mass can be utilized as TMD to absorb extra energy imparted on the structure during earthquake. The present work is limited to linear analysis of 10 & 15 storey buildings subjected to real earthquake data. Water tank position is changed by keeping it at center and at extreme corners of the building. Also effect of water tank as TMD with variation of sizes is checked.
