Research Abstract

The maintenance of the railway steel bridges is considered to be problems. Therefore, in this study, to be easy to come to do maintenance, the partial members of steel bridges are composed with concrete members. The stiffness increases from the bridges of only steel members. The remainder life of the structure is extended by this effect. These effects are confirmed by the experiments.
