장경간 도로/철도 병용교량의 열차주행안전성 확보를 위한 설계기준 분석

Road/Rail Bridge is important to minimize the vertical and lateral deformation of structure by road load and train load. In this study, it is performed the analysis of design specification for live load on road/rail bridge and considered the key issue point of rail view. Also, we referred the serviceability criteria for rail. Specially, because Eurocode don’t have live load application for loaded distance over 200m, long span road/rail bridge is necessary to extend classical code specification with rules adapted to the size and the specificities of the project. Thus, because live load is important in road/rail bridge, this paper was confirmed for the large influence of train load than traffic load and for live load than dead load.
