In steel plate girder railway bridges with open deck system, damage caused by local corrosion of the upper flanges under sleepers is well-known. This damage reduces ultimate strength of the main girders significantly (e.g., in the case of 50%-corrode

A lot of steel plate girder bridges were erected during the rapid growth in the 1960s in Japan. Currently, the condition of those aging bridges has become marked and a problem in society since over 50 years have passed. Particularly, the corrosion-in

In Japan, many steel railway bridges were constructed during the period of rapid economic growth in the 1960s. Now, as over 50 years have passed, the condition of these aging structures has become conspicuous, and a major social problem. In particula

In steel railway bridges with open deck system, the local buckling of compressive flanges under sleepers on plate girders caused by the local corrosion of flanges leads to the collapse of bridges. The local corrosion is thought to have a substantial

This study is targeted for the estimation method for the remaining life of a corroded truss bridge based on the ultimate strength through one of case studies. The remaining life can be estimated by the corrosion limit which is defined as a corrosion
