Water tank Seismic Analysis Noting Effect on time Period

Abstract

In the case of an earthquake, an elevated water tank is a crucial building component. In order to store water at a constant level, an elevated water tank is built and height for water distribution system pressurization. Uplifted water tanks, as was learned the hard way, suffered significant damage or collapsed during earthquakes. As a result of the raised water tanks' extreme sensitivity to earthquake parameters including peak ground acceleration, frequency contents, and duration records. The purpose of this study is to gain insight into the dynamic behavior of an elevated water tank fitted with a UG sump subjected to various recorded ground vibrations from earthquakes. An RCC square water tank with 14-, 17-, and 20-meter staging heights was subjected to a Time History Analysis using StaadPro software to simulate the effects of five distinct seismic ground movements. Roof displacement, velocity, acceleration, base shear, drift, and natural frequency were measured and compared for three different tank fill levels: empty, halfway, and full. Bhuj earthquake ground motion was the strongest, whereas Kobe earthquake ground motion was the weakest.
