Corrosion deterioration characteristics of the structural steel bridges, especially plate girder bridges are studied in this paper. The parts of bridges that are severely corroded are also investigated. Emphasis is placed on the prediction of corrosion (based on the steel exposure test, paint life, and corrosion ratio) of painted bridge members. The final aim is to find the effect of corrosion on the strength of painted bridge members.
