Bridges are composed by many structural members which interact with each other to resist against various load combinations. In the present study, full-scale FE analyses have been conducted for a steel I-girder bridge system with corrosion damages which have been removed each member. From the analytical results, it was found that when corrosion damage occurred at the end of the outer girder and the girder was loaded, the influence on the maximum load carrying capacity is large for the deck slab and the cross frames. When the corrosion damage ratio is low, the load sharing function of the cross frames increased near the damaged girder. However, when the corrosion damage ratio is high, the deck slab became effective, and the load sharing path changed depending on the degree of corrosion damage.
