  • Effect of rebar corrosion on the behavior of a reinforced concrete beam using modeling and experimental results = Vpliv korozije betonskega železa na armiranobetonski steber z uporabo modeliranja in eksperimentalnih rezultatov

    Reinforcement corrosion in concrete may cause adverse effects, such as the area reduction of rebars, concrete cracking, a reduction of the bond strength and a change in the bond-slip behavior between ... concrete and rebars. All these effects will finally lead to the inappropriate performance of concrete structures. In this paper a corroded reinforced concrete beam, whose experimental results are available, is modeled based on the finite-element method using ANSYS. The results are then compared with the available and confirmed results. A reduction of the reinforcement area and a change in the bond strength between the concrete and the reinforcement are seen in the model. The effect of reinforcement corrosion on the force-displacement curve and the modeled beam are also studied and compared with the results from reinforced concrete made in the laboratory. It was observed that with an increase of the reinforcement corrosion rate, the load-carrying capacity of the concrete beam and the bond strength decreases. In addition, the area under the load-displacement curve of the concrete beam decreases with the increase of the reinforcement corrosion.
