| Abstract: |
Railway steel bridges, which exceed their design lifetime, are increasing in Japan and some of them have problems such as corrosion, fatigue and noise. In this study, we proposed a method to improve a structural system of the steel bridges by integration with concrete decks. This method improves the load-carrying capacity of the girders, extends the service life, and reduces the noise. This paper describes the proposed method of concrete deck installation, connection between steel girders and concrete decks, and loading tests of girder-deck connection. |
