초록

The high speed train service will be offered for high-quality transport service in existing railway by Korean National Railroad(KNR). Therefore, this paper presents the results of analysis carried out to determine the dynamic response characteristics of deck plate girder bridges which are representative elevated structures of existing railway and to evaluate their suitabilities for supporting Korea Train Express(KTX) trainsets in the speed range 0-250 km/h. Their dynamic characteristics are analyzed concerning structural safety, train-operation safety and passenger comfort. The simplified method for 2-dimensional train/track/bridge interaction analysis is utilized in the analysis of dynamic behaviors of deck plate girder bridges.
