Research Abstract

Variability in deterioration progress of reinforced concrete structures suffered from chloride-induced corrosion has been evaluated with the probabilistic approach. It has also been made clear how the variability in corrosion of reinforcement affects structural performance taking into account the differences in causes related to variations in materials properties and those in deterioration progresses. A probabilistic life prediction system was proposed based on the reliability on the deterioration progress and structural performance.
