Bond Strength Modelling of Corroding Steel Reinforcement in Concrete
Corrosion of reinforcement can significantly affect the bond strength between the steel bar and the surrounding concrete thus greatly reducing the load bearing capacity of the concrete structure. In this paper, a simple analytical model is proposed to evaluate the maximum bond strength of corroded concrete with varying rebar diameters and concrete cover thickness. Predicted results compared well with experimental test data.
