Title: Improvement on Analysis of Track-Bridge Interaction
Abstract: In case of the continuous welded rail(CWR) track is supported by the railway bridge not earthwork section, the additional axial force and displacement are occurred in the CWR due to the track- bridge interaction. Three of important loads((temperature variation in the bridge-deck, braking/acceleration and the vertical load from the passing train) are considered as the independent loading case in the domestic design code, and the answer of each loads are simply added. Errors due to non-linear behavior of longitudinal load occurred between track and bridge-deck are also included ignoring the effects of loading history, and using the maximum value of load. In this study, the modified analysis method was proposed considering the effects of loading history.
