Reinforced concrete tanks are currently used for storage of different substances and products. Such as bulk material but also various liquid and gaseous substances. Most often they serve as reservoirs for drinking water, for wastewater treatment and storage of various technical liquids. Rectangular tanks are less used as cylinders, but they have their advantages, less sensitivity to unilateral load, and better use of space for a multi-tank system.
The rectangular tank solved in this article is filled with water. The rectangular tank solved in this article is filled with water. We are interested in dynamic tank analysis when considering its interaction with subsoil (SSI - Structure-solid-interaction). There are more options to consider SSI. In this article, the most commonly used model of the substrate, the one-parameter Winkler model, was chosen. Dynamic analysis consisted of two steps - modal and spectral analysis. In the modal analysis we determined the values of the frequencies of eigen shapes. The spectral analysis followed, where we focused on the magnitude of deformations and moments in the walls. We compared the obtained values of the rigid supported tank with the case of the placement of the tank on the flexible subsoil. The FEM-based software ANSYS has been used for the calculations presented in this paper. |
