초록

Based on the test run of next generation high speed train which is called HEMU-430X, bridge serviceability is investigated through measurements of vertical displacements of a steel composite bridge. In the present paper, a steel composite bridge which has 50m span length are reported. Vertical displacements of the bridge according to the gradually increasing speed are investigated and compared with interaction analysis results.
