Zur Einspannwirkung von Eisenbahngleisen

Abstract: Die Systemsteifigkeiten von Eisenbahnbrücken werden durch die über die Brückenenden hinauslaufenden Gleise positiv beeinflusst. Gemäß aktueller Normenlage lässt sich dieser Effekt im Modell durch ein separat vom Überbau modelliertes Gleis abbilden, das über nichtlineare Längsfedern mit dem Überbau bzw. dem anschließenden Dammbereich verbunden wird. Eine Systemvereinfachung mit einer linearen horizontalen Ersatzfeder, welche den Beitrag des Dammbereichs abbildet und sich für die Modellierung eines Einfeldsystem… Show more

“…The consideration of the longitudinal track-bridge interaction (TBI) also considerably influences the calculated dynamic behaviour of railway bridges. Besides the prediction of bridge vibrations, realistic stiffness properties of the longitudinal TBI are required in particular for the prediction of permissible rail stresses [5,6], whereby the consideration of the embankment area before and after the bridge also has a noticeable influence on the calculation results [6][7][8][9].…”
