Investigation on dynamic behaviour of conventional railway bridge subjected to high speed train loading

고속열차 주행에 따른 기존철도교의 동적거동 특성분석

The purpose of this paper is to examine the validation to passage of high speed train on conventional railway bridges. The dynamic behavior of bridge is analyzed by using the developed 3-D program. The train is assumed to moving loads and track to distributed masses. The centrifugal force due to curved track is also considered. The numerical results are compared with those measured in the site to demonstrate the efficiency of the developed program. From the parametric study, it is notified that conventional bridge gives good serviceability to passage of high speed train, specially such as TGV-K.
