Comparative Assessment of Advanced Computational Tools for Embankment-Abutment-Bridge Superstructure Interaction

Abstract eng:
The scope of this paper is to investigate the range of applicability of the advanced computational tools currently available for the dynamic analysis of bridge structures accounting for embankment- foundation-abutmentsuperstructure interaction. Along these lines, four different analysis approaches are adopted and independently applied for the study of a real, already built overcrossing 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. The results indicate that the last generation of computational tools available, certainly contribute towards the representation of the soilfoundation-bridge system as a whole and thus, the more accurate study of interaction problems that was not feasible to be examined in the past.
