Abstract: The article considers the problem of determining the stress-strain state of the tank wall in the area where it connects with receiving and dispensing pipes (PRP). One of the significant factors influencing the overall stress-strain state of the tank wall, which is a thin shell according to fundamental laws of structural mechanics, is the presence or absence of settlement of the bases and foundations of the structural elements of the tank. The article uses both classical structural mechanics methods, and existing analytical solutions. In addition to applying numerical methods, particularly the finite element method (FEM), implemented through the ANSYS software package The developed numerical model of the RVSP-20000 tank using the finite element method in ANSYS PC allowed to determine the displacements, deformations, and stresses in the structures in the junction area of the receiving and dispensing pipe and the RVSP tank wall. The numerical calculations revealed. As the numerical calculation in this article using the FEM complex has shown, the PRP, which has a connection with the reservoir at the level of maximum radial displacements of the wall from the hydrostatic pressure of the stored liquid, creates a significantly altered and potentially hazardous stress-strain state in the contact zone. This highlights the necessity of monitoring potential incompatible deformations in the foundations of both the PRP and the reservoir itself, and, if needed, implementing appropriate engineering measures.
