Title:Performance of Steel Girders Repaired with Advanced Composite Sheets in a Corrosive Environment: A Multi-Physics Approach Leading to Practical Design Recommendations
Principal Investigators:Yail "Jimmy" Kim
University:University of Colorado Denver
Grant #:DTRT13-G-UTC38 (MAP21)
Project #:MPC-456
Keywords:bearing capacity, carbon fibers, corrosion, fiber reinforced polymers, girder bridges, sheets, steel bridges


The objectives of the research are: 1) to understand the mechanism of corrosion progression in CFRP-repaired steel bridge girders exposed to a corrosive service environment; 2) To 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) to develop practical design guidelines for bridge engineers who are interested in repairing in-situ bridge girders with CFRP materials.
