The results of the mathematical modeling and experimental studies for the stress-strain state of the annular section of the reinforced concrete shell with the protective structure are presented.  Computer simulation has been formulated as a stationary temperature problem.  The distribution of deformations and stresses is shown using the equations of the elastic theory.  A comparison of theoretical dependences on the results of experimental studies of physical models is given. Conclusions are drawn about the possibility of using them in the calculations of reinforced concrete protective structures.
