The article describes the current state and the level of research of annular cross-sections of structures of energy facilities operating under conditions of thermal and force effects. The results of a numerical experiment to study the deformability and crack resistance of annular сross-sections and their comparison with the results of testing physical models of fragments of reinforced concrete chimneys are presented. It is shown that at the modern level of development of the mathematical apparatus and computer calculation programs, using the deformation model, the deviation does not exceed 20%. The described research results of other authors and this work confirm the possibility of replacing cost and long-term field tests with numerical experiments.
