Abstract: Poor concrete durability and corrosion of reinforcement bars are the primary cause of structural deterioration of reinforced concrete (RC) structures subjected to aggressive environments. For the management of deteriorating RC structures it is necessary to assess the remaining safe and service life using structural reliability theory. The uncertainties related to structural performance prediction of RC structures under corrosion can be reduced by the effective use of information obtained from visual inspections or field test data.
A procedure for obtaining the failure probabilities of RC structures in a marine environment updated by a nonlinear filtering technique, denoted Sequential Monte Carlo Simulation (SMCS), is indicated in this study. For illustrative purposes, this procedure is applied to a one-way RC slab. The corrosion crack width by visual inspection and deflection during a load testing are used as observational data. Using SMCS, multiple random variables related to observation information can be updated simultaneously. This paper demonstrates how lifetime reliability assessments can be updated with visual inspection or filed test data.
