초록

The appliance of the material characteristic of steel and concrete to the composite bridges is generalized in these day. As general rule, the steel plate girder bridge is the typical structure of the composite bridges, and the design codes is established. The several experimental programs regarding CFT composite section and non-CFT composite section are performed to obtain the flexure capacity and the performance of the filled-concrete in order to propose the new way of designing the composite bridge. Also, the specification of the CFT composite bridge for railway is not yet established and proposed, therefore, the concerning the specific characteristic of the CFT composite bridge, the design specification is proposed for the railway.
