Abstract-– Circular overhead water tanks are large storage containers constructed for storing water supply at certain height to pressurize the system of water distribution. It comprises of a heavy water mass at the top of a slender staging which is utmost critical parameter consideration for the collapse of the tank. A detailed understanding of the performance of the structures under dynamic forces is necessary to meet the safety objectives during construction and maintenance. Other modes of failures considered are sloshing damage at roof, buckling, inlet or outlet pipe breaks. From previous studies it was clear that inadequately designed tanks were damaged heavily due to improper design. This may be due to the lack of knowledge regarding the behavior of supporting system of the tank, and also due to improper selection of geometry of staging patterns. From the study it is concluded that the primary mode shape of circular tank is torsion which needs to be eliminated. To eliminate the torsion mode shape in circular elevated water tank, orientations of columns are modified. Circular water tanks are constructed in order to provide required head so that the water will flow under the influence of gravity the construction practice of water tanks is as old as civilized man. The water tanks project have a great priority as it serves drinking water for huge population from major metropolitan cities to the small population living in towns and villages.
