description: Steel vertical tanks are widely used for storing oil and petroleum products. The methods currently used by engineers to calculate the strength of such structures do not take into account many factors, for example, uneven soil settlement, the mutual influence of deformations of the wall and bottom. The relevance of the topic is determined by possible environmental and economic problems in the event of an accident. A mathematical model for calculating the strength of a tank based on the theory of rods is proposed. The stress-strain state of a steel tank under the influence of static oil pressure is determined. Dependences of maximum mechanical stresses in the tank on the level of liquid in it and on the stiffness of the base under it are constructed. The calculation of the tank weakened by hydrogen influence is carried out: the zones of hydrogen degradation of the material are determined and the arising stresses are calculated.
