Performance of Steel Girders Repaired with Advanced Composite Sheets in a Corrosive Environment: A Multi-Physics Approach Leading to Practical Design Recommendations

The objectives of this research project are to: (1) understand the mechanism of corrosion progression in carbon fiber reinforced polymer (CFRP) repaired steel bridge girders exposed to a corrosive service environment; (2) examine the effect of corrosion damage on the performance of repaired steel girders in terms of load-carrying capacity and ductility as well as CFRP-steel interfacial behavior; and (3) develop practical design guidelines for bridge engineers who are interested in repairing in-situ bridge girders with CFRP materials.
