    Abstract

    Analysis of hydrodynamic structure such as elevated concrete water tank is quite complicated when compared with other structures. As well as dynamic fluid-structure interaction (FSI) plays an important effects in this complexity for which research suggests solution by using different methods. This paper presents the dynamic behaviour of elevated concrete water tank with three degree freedom modelling of liquid i.e. convective, impulsive and rigid mass. Three models of varying capacity with varying staging height are analysed with fixed base and corresponding responses are reduced by applying two types of base isolator. Base isolator used are LRB and Lead LRB. Imperial Valley 1940 El-Centro Earthquake ground motion has been used for generating the various response of the tank. The base shear, displacement of convective mass, displacement of impulsive mass, displacement of base has been calculated for non-isolated tank and compared with non-isolated tank.
