Condition Assessment of RC Bridges Using Reliability Model Incorporating Health Monitoring System (original) (raw)

Bridge management systems call for realized and efficient performance prediction methodologies to optimize the resources used in bridge inspection, maintenance and repair. A spatial time-dependent reliability model for performance prediction of reinforced concrete bridges exposed to corrosion is presented. This model can be considered as the core of a methodology for performance updating of deteriorating concrete bridges. The proposed methodology is based on the Bayesian analysis and utilizes data reported by health monitoring systems. It helps to evaluate the reliability of a reinforced concrete bridge exposed to corrosion. It was found that the proposed probabilistic reliability model incorporating health monitoring system improves the future corrosion damage predictions with more accuracy and less variability.
