Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport

Sammanfattning: The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. One key aspect to consider is the impact of track irregularities, which are imperfections in track geometry. These irregularities have a significant dynamic impact on bridge responses during train passage and are addressed in the regulations through a dynamic amplification factor (DAF)
