A software prototype for assessing the reliability of a concrete bridge superstructure subjected to chloride-induced reinforcement corrosion

摘要: A software prototype is developed for assessing and updating the reliability of single-cell prestressed concrete box girders subjected to chloride-induced reinforcement corrosion. The underlying system model consists two integrated sub-models: a condition predicting deterioration state girder structural evaluating overall reliability. based on dynamic Bayesian network (DBN) which considers spatial variation corrosion process. Inspection data are included in calculation through basis DBN model. To demonstrate effect partial inspections, applied case study typical highway bridge with six spans. illustrates that it possible infer uninspected parts structure due correlation (Less)
