An elevated water tank is a water storage container constructed for the purpose of holding water at a certain height to pressurize the water distribution system. Water tanks are very important components of lifeline. They are critical elements in municipal water supply, firefighting systems and in many industrial facilities for storage of water. Elevated water tanks are critical and strategic structures and damage of these structures during earthquakes may endanger drinking water supply, cause to fail in preventing large fires and substantial economic loss. A large number of overhead water tanks were damaged during the past earthquakes. Hence seismic behavior of these structures during the earthquakes has to be investigated in detail in order to meet the safety objectives while containing construction and maintenance costs. In the present study, an elevated RCC rectangular water tank was modeled and analyzed using the ANSYS software. The static structural, modal and transient (using the accelerogram of the 1995 Kobe earthquake as input) analyses were conducted, and the response behaviour of the tank with 100%, 75%, 50% and 25% water fill conditions were studied. It was observed that the responses of the tanks elevated with an increase in the water heights.
