Seismic Analysis of Water Tank with Different Configuration to Find Optimal Solution

A Water tank means a container to store water in a huge amount of capacity. As known from experience, liquid storage tanks collapsed or are heavily damaged during earthquakes all over the world. The economic lifetime of ESR is generally around 40–65 years. Damage or collapse of the tanks causes some unwanted events such as shortage of drinking and utilizing water, uncontrolled fires, etc. Therefore, to avoid all those disadvantages numerous or various studies are being carried out regarding tanks. In this study, I have compared reinforced cement concrete Elevated Service Reservoir (E.S.R) of Square and Circular shape of 1 lakh capacity and a total height of 12.6 m with 3 m staging in Earthquake Zone II, III, IV, and V by Equivalent static analysis using ETABS software for base shear and deflection guidelines for the design of the tank and IS 1893-2016 code. It can be seen that a Circular water tank is more economical and preferable.
