ABSTRACT

In modern societies, transports play a crucial role in economic growth and globalization. Among the other transports, High speed trains can be more competitive for distances about 100/200 km and 400/600 km, comparing with terrestrial and aero transportation, respectively (Ureña, 2010). However, with the increase of high speed trains usage, some resonance problems were identified (e.g. ballast liquefaction due to high accelerations produced by the passage of the trains (Gustafsson, 2008)), being essential to evaluate the bridge response due to their passage. Bridge’s safety studies should be performed through dynamic analyses.
