The problem of the limiting states occurrence in the structures of a vertical steel tank is investigated in this work.To study the SSS of the metal structures of the object, the authors created a numerical model Mains Block Base of the RVS-20000 tank in the ANSYS software complex.The model considers the maximum number of elements with their geometry and connections affecting the tank SSS under non-axisymmetric loading, including beyond the elasticity of steel.Dependences between the parameters of intrinsic stiffness of the VST are obtained.The results of the finite element analysis made it possible to develop a technique for assessing the technical condition of the structure with the development of irregular subsidence of the external bottom contour.

The M JACKETS proposed technique can be used by both operating and design organizations in making managerial decisions regarding the repair of RVS-20000 subjected to the base subsidence.
