Modelling of ground-supported storage container using FEM

Ground-supported cylindrical tanks are used to store a variety of liquids. This paper provides the theoretical background for numerical simulation by application FEM ALE FSI. Two models were used for calculating response of concrete open top rectangular liquid storage tanks - chipping channel. It was performed by application FEM (Model S) and FEM ALE FSI (Model F). The former uses an alternative approach of numerical FEM simulation where only solid domain of tank was modeled by FEM and the effect of fluid interaction was simulated as the static load acting onto the walls and the bottom of the tank. As an example case we will assume the ground supported rectangular endlessly long concrete shipping channel filled with water, without roof slab structure covering the channel and grounded on hard sub-soil.
