Description In this paper, expert judgement regarding corrosion damage level is integrated with the structural risk, expressed in terms of probability of attaining a particular damage level, for the remaining life assessment of corrosion affected reinforced concrete structural members. In the proposed methodology, the thinking process of the expert, in corrosion damage assessment, is modelled within a probabilistic framework using Brunswikian theory. The performance of each expert is determined by computing the achievement index. The damage assessment procedure is integrated with Markov Chain model for risk-based remaining life assessment. To illustrate the usefulness of the proposed methodology in determining more rationally the remaining life, an example problem of remaining life assessment of a reinforced concrete bridge girder is considered.
