A Comprehensive Reliability-Based Framework for Corrosion Damage Monitoring and Repair Design of Reinforced Concrete Structures

This study proposes a framework to develop an effective reliability-based model and management system for the corrosion dynamics in the corrosiondamaged reinforced concrete that relates the corrosion process with the corrosion precursors from the environment and inherent to the material with time. The proposed framework will be tied to a reliability-based service life prediction model of reinforced concrete structures where corrosion is detected and the uncertainties inherent within its influencing parameters are quantified. The quantified uncertainties in the parameters that influence the corrosion process will be used to calibrate design factors used in structural design for repair and load rating of corroding reinforced concrete structures using reliability-based service life prediction models. The developed model will conform with inspection practices and reliability concepts by Department of Transportation (DOT) to facilitate implementing the research results into the DOT Integrity/Reliability Management System for use by DOT as well as local counties/parishes, cities, and townships in the Southern region.
