2E24 A study on the influence of track irregularity on the dynamic interaction between the vehicle and the steel girder bridge(Infrastructure)

Abstract

In this study, in order to clarify characteristics of dynamic wheel load on open steel girder bridge, a numerical simulation of the dynamic interaction between vehicle and bridge has been carried out focusing on open steel girder bridges. Consequently, it has been clarified that the correlation between the curvature of the track irregularity and the maximum wheel load is not a simple proportional relationship by influence of beam deflection on steel girder bridges.
