A study on the influence of the reinforcing bar corrosion level on the flexural crack’s width in the existing structure is presented. Parametric studies of the crack width development of corrosion damage were performed using a block model for the reinforced concrete element with corroded bars. The analytic description of the bond-slip law «t-s» and the establishment of the parametric points of this diagram are decisive in this model. Using the block model, the distribution of the concrete ε ct (x) and reinforcement εs(x) strains for the different level of corrosion damage, normal crack width was obtained and the effect of the level of corrosion damage was established.
