Abstract

In this paper, we introduce the Partial Half-Through Type Plate Girder Bridge proposed by Hyundai Development Co. and KRTC Consortium in Turn-Key Based design last year, and this type of bridge may be adapted to the railway bridge under similar conditions. This bridge across the North Han River was to be concerned its find view and the protection of water source. For its location is inside the dam, it required the long span and the clearance for the flood also. Its new composite section was able to diminish the deflection and vibration. Its shop-fabrication could control its quality easily, and might to be launched. This structural type have satisfied its functions, construction situations, and overall safeties, so this is the field-oriented type. However the composition and connections of the proposed members are different to the recent forms, and difficult to be applied to present specifications. Therefore it requires a certification on the application for more safety by not only analytical verifications but also experimental studies. Nevertheless, this type of bridge may have some more applications from now on.
