Abstract 1. This paper presents the results of a nonlinear finite element analysis to determine the remaining ultimate strength of a ferry bridge with local corrosion at the girder flange. The ultimate strength decreases with the corrosion thinning of the flange, when the corrosion damage locates at the center of the span. On the other hand, when the corrosion damage exists near the support, the ultimate strength did not decrease, which shows the repair of the flange thinning near the support is not so effective in strength rehabilitation of the bridge. The reason of these facts is
2. the collapse of the bridge is due to bending moment in the former case, but in the latter, it is due to not bending moment but shear force, therefore, flange thinning does not concern with the shear strength. Thus, rational maintenance will be possible after clarifying the collapse mode and the remaining strength of the bridge
