Earthquake Analysis of Water Tank for Different Staging Height and Sloshing Effects

from the old experiences of few earthquakes, like Bhuj earthquake in India elevated water tanks were heavily harmed or failed. Liquid loads behave very differently to dry loads at the time of earthquake. When the liquid starts to slosh in the tank, it causes huge weight shifts. Elevated water tank must remain functional after earthquake as it is useful to provide water and firefighting system, Therefore it is important to study in detail. This paper presents study of earthquake analysis of elevated water tank for different staging height having the same capacity. It is necessary to have a control system for effectively reducing slosh. The purpose of this study is to know the behavior of liquid under motion or vibration by comparing sloshing frequency numerically, experimentally and by ANSYS. And also to analyze model of water tank with different bracing patterns, staging heights to know the minimum deflections.
