The credibility of lifetime assessment based on few experimental measurements

Garavaglia, Elsa [Politecnico di Milano] Sgambi, Luca [UCL]

Recently an index of credibility has been introduced by Grandori et al. (2003) in order to measure the variability of an estimated hazard quantity. On its basis a probabilistic hazard model can be constructed reducing some aleatory uncertainties. In this paper the definition of the credibility index is extended to the lifetime assessment of reinforced concrete struc-tures affected by deterioration over time.
