A nonlinear method of dynamic calculation of a reinforced concrete beam is developed, based on a discrete model with corrosion damage and rheology of deformation. Corrosion damage is taken into account by reducing the coefficients to the calculated mechanical characteristics of concrete and reinforcement. Presented the results of the calculation of a reinforced concrete beam with and without taking into account corrosion. Noted that the corrosion damage and the non-linearity and non-equilibrium deformation of reinforced concrete structures under dynamic influences allows us to more fully accounting the real work of materials. Without taking into account corrosion Analysis of the results of the calculation of a reinforced concrete beam in the resonant region of vibrations at the first frequency of natural vibrations shows that the amplitude-frequency characteristic becomes nonlinear and the frequency of resonant vibrations becomes dependent on the amplitude of vibrations. The comparison of the calculation results with the experimental data showed a satisfactory convergence.
