Item 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.
