Life cycle performance of corrosion affected RC structures is an important and challengingissue for effective infrastructure management. The accurate condition assessment of corroded RC structuresmainly depends on the effective evaluation of deterioration occurring in the structures. Structuralperformance deterioration caused by reinforcement corrosion is a complex phenomenon which is generallyuncertain and non-decreasing. Therefore, a stochastic modelling such as the gamma process can be aneffective tool to consider the temporal uncertainty associated with performance deterioration. This paperpresents a time-dependent reliability analysis of corrosion affected RC structures associated bond strengthdegradation. Initially, an analytical model to evaluate cracking in the concrete cover and the associated lossof bond between the corroded steel and the surrounding cracked concrete is developed. The analytical resultsof cover surface cracking and bond strength deterioration are examined by experimental data available. Thenthe verified analytical results are used for the stochastic deterioration modelling, presented here as gammaprocess. The application of the proposed approach is illustrated with a numerical example. The results fromthe illustrative example show that the proposed approach is capable of assessing performance of the bondstrength of concrete structures affected by reinforcement corrosion during their lifecycle.
