Dynamic Analysis For the WPC Girder Bridge

초록

This paper presents the findings obtained from the numerical analysis investigating into the dynamic characteristics of a railway bridge that adopts the Wide-flange Pre-stressed Concrete (WPC) girder. The analyses have been carried using the loading that would be developed when the high-speed train, i.e. the Korea Train eXpress, is passing. The analyses were carried out using a speed increment of 10km/hour, and up to the speed of 380km/hour, which is 1.1 times greater than the top speed of the train. The results suggested that the railway bridge with WPC girder met the design criteria recommended by the relevant design criteria.
