The problem of modeling the behavior of reinforced concrete cylindrical shell under conditions of radiation exposure is considered. Solving equations for the shell are obtained, taking into account the joint action of the load and radiation exposure. It is believed that the mechanical characteristics of concrete and reinforcement depend on the radiation dose. The work of concrete on tension and compression is also taken into account. In the output, a method is used to replace the discrete reinforcement in each direction with an equivalent layer. To solve the equations, it was suggested to use a time-stepping technique with finding at each step the law of distribution of the irradiation dose over the body of the shell, the swelling deformation, and according to them the laws of distribution of the mechanical characteristics of concrete and reinforcement, taking into account the effect of irradiation and the nature of the stress state.
Keywords: reinforced concrete cylindrical shell, radiation exposure, dose of radiation, radiation swelling.
