Dynamische Berechnung von Eisenbahnbrücken im Zuge von Hochgeschwindigkeitsstrecken – Ein alternatives Verfahren zur Simulation von Zugüberfahrten

Abstract: 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 parametric dynamic analyses were performed using linear modal analysis techniques. Thereby, the system of differential equations is de-coupled into a series of ordinary differential equations, each representing the response of a "modal" single degree of freedom (SDOF) mass-spring system [2]. Linear structural behavior and linear viscous damping are assumed for this type of analysis.…”

“…Linear structural behavior and linear viscous damping are assumed for this type of analysis. By solving the individual ordinary differential equations for the SDOF systems analytically for the passage of a single axle, and using the superposition principle to determine the cumulative effect of multiple axles, great computational efficiency can be achieved; an application of this method to bridges in the Austrian federal railway system was described in [2]. In a recent graduate thesis [3], this method was prepared for use in systematic parametric studies.…”

“…Alternativ dazu werden auch die wesentlich effizienteren kombiniert numerischen und analytischen Lösungsverfahren, wie z. B. das von Pircher vorgestellte Verfahren der analytischen Zeitschrittintegra tion, angewendet [6]. Zur Berechnung der Tragwerksantwort bei Zugüberfahrt werden als sehr gute Nä he rungs verfahren im Fall von beidseitig gelenkig gelagerten Brücken und Modellierung als Balken auch die im ERRI D 214/RP 6 [7] angegebenen DER-und LIR-Methoden angewendet.…”

“…The dynamic calculation of the structural responses resulting from train crossing simulations is usually carried out with finite element programs, whereby the equations of motion are solved by application of modal or direct time-step integration. Alternatively, the much more efficient combined numerical and analytical solution methods, such as the analytical time-step integration method presented by Pircher [6] or the DER-and LIRmethod presented in ERRI D214/RP 6 [7] are also used.…”
