The paper presents the results of investigations obtained within the project B2 of the research group DFG FOR 537 “Modeling reinforcement corrosion”. In the project the influence of corrosion on the in- teraction between steel and concrete is investigated. The experimental and numerical investigations are con- ducted on ‘beam end’ specimens. The paper presents the results of numerical investigations and their com- parison with experimental results. The bond strength together with corresponding end displacement at reference state and different corrosion levels are modeled and compared with experimental results. Specimens without stirrups show strong reduction of bond strength with increase of corrosion level. In contrary to this, bond strength of specimens with stirrups is much less sensitive on the corrosion level of reinforcement. The numerical results are in good agreement with the experimental observations.
