초록

In case of the concrete track on the special bridge such as arch bridge are subjected to the temperature variation, there is a some vertical displacement of the track. In general, construction temperature of bridges and tracks is equally controlled by considering the air temperature variation of the construction site. In some case, however, the construction temperature difference between the bridge and track may be occurred. In such cases, difference of the vertical displacement of the track may occur depending on the analysis method such as step by step analysis or completion stage analysis. In this paper, in order to investigate the vertical displacement of the track according to the step by step analysis and completion stage analysis, FE analysis are conducted.
