Comparison of Intensity Theoretical Calculation with Finite Element Calculation for the Below Node of Storage Tank Wall

Simplified theoretical method is used first to calculate the intensity on the wall of storage tank, and then FEM technique is applied to numerical calculation of levels and distributions of stress and strain on the same one. A results comparison between two methods are made, which shows that there exist big errors in the results by simplified theory method, thus an amendments for the theoretical calculation is putted forward, and a conclusion that the finite element method for stress and strain analysis on the wall of storage tank is more in line with the needs of the practical engineering application is pointed out in the paper.
