Research Abstract

This study presents a framework for estimating the remaining lifetime of reinforced concrete structures in a marine environment based on the observation information such as visual inspection of corrosion cracks and chloride concentration distributions. Random variables used in the prediction of corrosion process of concrete component could be updated by Sequential Monte Carlo Simulation. In addition, growth process of steel corrosion was visualized by X-ray photography in order to understand the spatial distribution of corroded steel used in the proposed framework.
