STATIC ANALYSIS OF WATER TANK WITH AND WITHOUT SOIL INTERACTION USING ANSYS

Abstract

Elevated water tanks are one of the most important lifeline structures in earthquake prone regions. In major cities and also in rural areas elevated water tanks forms an integral part of water supply scheme. This study presents the evaluation of seismic forces acting on elevated water tank e.g. circular water tank with frame staging affected by different parameters viz., seismic intensity, different wind speeds. Seismic forces acting on the tank are also calculated changing the seismic zone of IS:1893-2002 for seismic design has been referred. Two types of water tank design here, water tank with soil and without soil designed. With the help of Solid work Water tank designed with soil and without soil interaction using ANSYS. In the present study attempt have been made to study the effect of soil structure interaction on the performance of water tank. Three dimensional FEA is carried out using ANSYS Software. In the present study use different Parameter to define mode shape and natural frequency and different type of stress pattern.
