A Comprehensive Uncertainty-Based Framework for Inspection Planning of Highway Bridges

Bridge inspection standards in the United States require routine visual inspections to be conducted on most bridges at a maximum interval of two years regardless bridge condition. Limitations this uniform calendar-based approach have been reported literature. Accordingly, objective study is provide new systematic for planning that integrates information from condition prediction models, data, and expert opinion using Bayesian analysis enhance efficiency maintenance activities. The uncertainty-based framework proposed can help owners avoid unnecessary or delayed repair actions, determine method, consider more than one deterioration process component during process. time method are determined based uncertainty risks associated with As reaches defined threshold, an scheduled utilizing nondestructive techniques reduce level. demonstrated existing reinforced concrete deck impacted by corrosion deterioration. results show number 50% compared conventional scheduling methods, regarding reduced 16%.
