Abstract

This paper proposes a symptom-based reliability analysis method for deteriorating reinforced concrete (RC) structures on the basis of monitored data. The structural flexural resistance due to reinforcement corrosion is selected as a symptom which reflects the deteriorating structural performance. The symptom reliability and remaining service life are then estimated from the Weibull model for the structural flexural resistance development. The results for the numerical study example show the proposed approach is capable of prediction the remaining service life for the deteriorating RC structures subjected to the reinforcement corrosion.
