Mit den neuen, EUROCODE-gemäßen Normen werden auch baudynamische Berechnungen neu geregelt. Ein Berechnungsverfahren, einfacher und schneller anwendbar als die übliche Zeitschrittberechnung, wird für den Anwendungsfall "Dynamik von Eisenbahnbrücken im Zuge von Hochgeschwindigkeitsstrecken" gezeigt. Dynamic analysis of high speed railway bridges. The new EURO-CODE-based design code regulations require attention to

The design of bridges is typically split into two, quite distinctly different stages: the design of the overall structure on the one hand; and the detailed design of the individual components on the other hand. Typically the overall design takes place on generalised and simplified models of the bridge structure. Section forces and displacements gained from such models are then used as boundary conditions for the much more detailed models used in the second stage. An integrated process whereby requirements for both design stages are incorporated into one model has in the past been made difficult or impossible by the lack of computing resources. This situation is about to change. Generally available computers will soon be powerful enough to allow such a holistic approach. This paper outlines the strategies employed in a current research project which provides the scientific background for such an integrated design approach. The outcomes of this research project are to be directly incorporated into a state-of-the-art bridge design software package. First results of this research project are documented and future developments are explained in this paper
