Comparison of deformations of the large floating-roof tanks with the results of long-term monitoring

Abstract

The basic requirements for settlement of steel vertical cylindrical tanks are given. The construction of such a foundation is considered and a method for calculating pile ring foundations of large- volume tanks based on the decisions of K.E. Yegorov and A.A. Bartholomei is proposed. The results of monitoring the settlement of a large-volume tank with a floating roof after the completion of hydraulic tests and three years after its operation are presented. The monitoring results are compared with the results of analytical calculations according to the proposed formulas and numerical methods (finite element method - FEM) for various software systems.
