In order to master the static characteristics of the super vertical steel storage tank structure, based on the potential flow theory, the fluid structure coupling element and contact element are introduced, and the three-dimensional finite element model of 150000m3 super large steel storage tank system is established by using the finite element software ADINA. The static analysis of the tank structure under different water filling height is carried out, and the circumferential and axial stress and distribution at different height of the tank wall structure are obtained. The results are in good agreement with the experimental results, and the rationality of ADINA finite element modelling method is verified. Finally, the stress nephogram and design suggestions of the wall of the super vertical steel tank are given, which lays the foundation for the further static and dynamic nonlinear analysis of the tank.
