N2  - The line track bearings used in the Yeoungjong Grand Bridge experienced cracks and deformations, which result in significant accelerations and displacements of the track. This study measured an acceleration and a displacement of 0.5 g and 0.5 mm, respectively. Three-dimensional finite element analysis was performed to predict the behavior of railway tracks. However, when low-maintenance cylindrical bearings were used instead of line bearings, the displacement was decreased by 93%, and the acceleration was decreased by 82%. Furthermore, it turned out that the maximum displacement of the track girder was decreased by 45% when cylindrical bearings were used.<p />  <p>Language: en</p>
