In order to improve the traffic congestion on the road, it is essential to construct overpasses and highways in big cities. In particular, in order to facilitate traffic flow within the overpass route, it is necessary to construct a curved bridge because the plane shape of the bridge itself must be aligned with the road alignment. Therefore, in this study, we have developed a precast PSC curved girder of concrete hollow box type with excellent bending moment, shear force and torsional moment resistance, and perform performance evaluation by structural test to confirm applicability to curved bridge.
