ABSTRACT
Ground-supported tanks are used to store a variety of liquids. The fluid develops hydrodynamic pressure
on walls and bottom of tank during an earthquake. This paper provides theoretical background
for specification of impulsive and convective actions of fluid in liquid storage rectangular container
by using analytical methods. Numerical model of tank seismic response - the endlessly long shipping
channel was obtained by using of Finite Element Method (FEM), Arbitrary-Lagrangian-Eulerian
(ALE), Fluid Structure Interactions (FSI) formulation in software ADINA. The results of the analytical
methods and the numerical solution were compared for partially water filled channel grounded
on hard soil or sub-soil 30 MNm–3. It was considered the horizontal ground motion of the earthquake
in Loma Prieta.
