Abstract [en]

In the present approach the modelling of the corrosion process itself is avoided and only the effects of corrosion are taken into consideration. Accordingly, loss of steel bar section, longitudinal cracking and reduced bond are accounted for in the present corrosion model. Particular attention is given to the representation of bond stress-slip behaviour ofcorroded steel bars. The method developed herein is validated against published results from laboratory tests on medium scale beams with corroded reinforcement. The load-deflection behaviour obtained from finite element simulations are in good agreement with the test data. The modes of failure recorded in the laboratory tests were captured in the numerical simulations. It is believed that nonlinear finite element analysis can be developed into areliable tool for the assessment of serviceability and safety of reinforced concrete members suffering from steel bar corrosion
