Analyse des dynamischen Verhaltens des Eisenbahnschotteroberbaues - Einfluss der Schwingungsamplitude und anderer Randbedingungen auf das Steifigkeits- und Dämpfungsverhalten

Analysis of the dynamic behaviour of the railway ballast bed - Influence of the oscillation amplitude and of other marginal conditions on the stiffness and the damping characterists.

The pan-European establishment of an interoperable high-speed railway network places high demands on the existing railway infrastructure. Greater travelling speed results in increased dynamic excitations of the bridge structures. To investigate the dynamic interaction between the ballast superstructure and the structure of the bridge, experimental investigations were realised at the Institut für Tragkonstruktionen/Stahlbau der Technischen Universität Wien (Institute of Structural Engineering at the TU Vienna) during the last years.
