Abstract
Corrosion of a steel I girder bridge is often found at the girder end and researches to evaluate the load carrying capacity of the corroded girder end have been carried out. However, load carrying capacity of a bridge system corroded at the girder end is not clear, and seismic performance of the girder end is also unclear. In this study, load carrying capacity of a bridge system corroded at the girder end is examined by full scale FEM model. In the case with corrosion at the partial girder end, bridge system behavior, as the intact girder end shares load acting on the damaged girder end, is observed, and the resistance of the damaged girder is higher when considered as part of a bridge system.
