    Abstract

    A methodology is presented for the assessment of corroding reinforced (RC) beams using two dimensional finite element analysis (FEA). A sample number of experimentally tested, corroded beams found in literature are modelled and analysed using the FE program DIANA. Comparisons are made on the basis of, (a) Global structural response, i.e. load - deflection curves and (b) damage sequence, i.e. steel yielding, concrete crushing, etc. Non-linear behaviour of the concrete is described using a standard rotating smeared crack model based on a Fracture Mechanics approach. The main effects of corrosion are identified and modelled in the FE analysis. Particular emphasis has been given to the modelling of bond and its deterioration due to reinforcement corrosion. The results are found to be in good agreement with the experimental studies. The importance of considering the main effects of corrosion in the assessment of damaged RC structures is confirmed and some research needs within the area are identified.
