Corrosion of girder ends is one of the major damage for reducing the load carrying capacity of steel bridges. This research aims on proposing a practical method for evaluating remaining capacity of steel riveted girder end with section loss due to severe corrosion. Compressive loading test and elasto-plastic finite element analysis using two models were conducted for a girder end specimen which was cut out from a demolished old steel bridge in order to investigate the influence of the section loss on the remaining capacity and failure behavior.
