Abstract

Corrosion of reinforcement bars in two-span concrete beams was investigated using both experimental and finite element analysis.The experimental program comprised a total of twenty-two full scale reinforced concrete beams.The beams were divided into three equal groups of seven beams each, in addition to a non-corroded control beam. The three groups were initially loaded, before subjecting to corrosion, with a concentrated load at the middle of each span ranging from zero loading for group No. 1, to 40% and 60% of the ultimate load for groups No.2 and No. 3 respectively.The impressed current technique was used for accelerating the corrosion with a current intensity not exceeding 200 æA/cm2. The tension side at the middle of the beam was selected for corrosion to avoid uniform corrosion of the rebars along the beam. A finite element model was developed using the finite element code ABAQUS 6.14. A new model was proposed to model the behavior of concrete in compression and tension through the plastic portion of the stress-strain curve.The finite element model showed a good agreement with the results of the experimental beam
