摘要

Advanced computational tools are currently available for the dynamic analysis of bridge structures considering the complex phenomenon of embankment-foundation-abutment-superstructure interaction. Along these lines, analysis approaches of increasing complexity are applied for the study of a real, already built overcrossing along the Egnatia highway in Greece, each time making the appropriate assumptions and using purpose-specific software. Both single and multi-platform analysis is employed and the limitations and advantages of each approach are comparatively outlined and discussed in the linear and non-linear range. The results indicate that the last generation of computational tools available, is a promising alternative and certainly contribute towards the representation of the soil-foundation-bridge system as a whole and thus, the more accurate study of interaction problems that was not feasible to be examined in the past.
