Abstract
The existing regulatory framework does not cover the calculation of reinforced concrete elements subjected to corrosion. The calculation of such elements is given in a number of scientific papers. The article deals with a particular problem of calculation-finding the pressure of corrosion products and calculation of detachment of the protective layer. To solve this problem, the polar-symmetric problem was solved and formulas for determining the pressure of corrosion products, stresses and displacements were obtained. The condition of destruction of samples is received based on the theory of strength of G. A. Geniev. The calculations carried out on the obtained dependences have good convergence with the calculations taking into account the physical and geometric nonlinearities, performed in the universal software complex ABAQUS. An engineering method for calculating the separation of the protective layer was developed. The possibility of experimental confirmation of the calculations, as well as the need for additional research in the field of corrosion damages is shown.
