The corrosion is a main cause of degradation damage in the steel bridges. The evaluation whether the repair or reconstruction would be need or not for the corroded steel member, is based on cross section and quantity of corroded portion. It is considered reasonable that the evaluation will be base on the endurance of the corroded member. In this study, the bending endurance of the I-shaped steel girder with the local corrosion on the lower flange is discussed by using elastic-plastic finite element analyses. That simple way of estimating it is also proposed.
