The article discusses the issues related to the operation of compressed corroded reinforced concrete elements under dynamic (shock) impacts. The experimental data of the samples subjected to flow-accelerated corrosion are presented. Modeling of such samples was carried out by means of the Ansys software package. In this paper we present a static and dynamic calculation of the experimental samples in the Ansys software package. The breaking load comparison of the samples obtained during the experimental tests and in the Ansys software package, which has fairly good convergence, is made. The comparison of the experimental and obtained as a result of calculation in Ansys diagrams of the corroded-damaged reinforced concrete element and tensile reinforcement concrete compressed zone deformation is presented. The values of dynamic hardening coefficient were obtained for the first time depending on the corrosion damage section’s length.
