As for steel bridges, corrosion of girder ends is one of the major damage for reducing the load carrying capacity. This research focuses on proposing a simplified approach for evaluating remaining bearing capacity of steel plate girder end with section loss due to corrosion. Laser surface measurement of corrosion depth and compressive loading test were conducted for a girder end specimen which were cut out from a demolished 90-year-old steel railroad bridge in order to investigate the influence of the section loss on the remaining capacity. Also parametric finite element analyses for remaining capacity of girder end were carried out considering typical section loss patterns with various depth and discussed a practical method for estimating remaining capacity.
