Fatigue Notch Factor in Steel Bridges Due to Corrosion

In this paper the main aspects that are associated with stress concentration created by corrosion are reviewed and separate functions are produced for fatigue notch factor in terms of average corrosion penetration and exposure time. In particular, the relation of fatigue notch factor in terms of exposure time gives a direct, accurate, and quantifiable assessment of corroded members and it needs only the time of weathering. Finally the fatigue notch factor of corroded steelwork compared with the fatigue notch factor of various classes of structural detail as classified in BS 5400, the UK code requirements for fatigue.
