Assessment of Serviceability Based on Corrosion Cracking during a Long-Term Chloride-Induced Corrosion

Article Preview

In this paper, a non-destructive analytical method was proposed to predict the serviceability of corroded RC structure from corrosion cracking. Two models of corroded reinforced concrete were proposed to take into account the influence of corrosion pattern. Based on a three-phase model linking corrosion cracking and reinforcement corrosion and the transfer length, the models allowed quantification of the effect of the steel cross-section loss and the deterioration of the steel-concrete bond. Using a macro-element FEM analysis, the serviceability models were performed on a corroded beam stored in a chloride environment under sustain loading to predict the deflection of mid-pan under service load and compare with the experimental results.
