    Sloshing Response of Water Tanks Under Seismic Excitation
    (Springer Science and Business Media Deutschland GmbH, 2022) Jogi, J.; Jayalekshmi, B.R.
    Liquid storage tanks are the predominant structures and they have to be designed to withstand major earthquake loads. In the present study, an elevated intze water tank of capacity 700 m3 was considered and analyzed for seismic effects. Finite element modeling of the tank was made in ANSYS. A series of transient analyses was carried out for El Centro and Kobe earthquakes which are applied in the horizontal direction. The fluid inside the tank accelerates and causes additional hydrodynamic pressures on the tank. Past studies reveal that the convective hydrodynamic pressure is more than the impulsive hydrodynamic pressure. Time history plots were made to describe the sloshing phenomenon in the tank for various levels of the liquid. The sloshing displacements for the one-third level of the liquid were found to be maximum. The sloshing displacements in the horizontal direction are more than in the vertical direction. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

    Dynamic Response Analysis of Fluid Storage Tanks Using Coupled Acoustic-Structural Approach
    (Springer Science and Business Media Deutschland GmbH, 2024) Giridhar, P.; Jogi, P.; Jayalekshmi, B.R.
    Industrial fluid storage tanks are exposed to significant damage in earthquakes and cause the destruction of life and property. The seismic response of fixed-supported, three-dimensional rectangular rigid and flexible fluid storage tanks is analyzed using the finite element method. In this study, the fluid storage tanks are examined by utilizing coupled acoustic-structural (CAS) models. The convective displacement behaviors of rectangular liquid tanks are studied numerically under harmonic and earthquake excitations. The tank fluid–structure interaction (FSI) performance is studied by applying CAS methodology. Convective displacement, convective pressure component, impulsive pressure component, and total hydrodynamic pressures are analyzed for square and rectangular liquid storage tanks, and it is found that rectangular fluid storage tanks have more sloshing displacement and impulsive pressure component compared to square liquid storage tanks. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
