Abstract
The scope of this paper is to investigate the importance of various modelling assumptions on the overall seismic response of twin bridges (i.e. bridges constructed with two, almost identical branches) considering the coupling and dynamic interaction of the deck-abutment-backfill-embankment and superstructure-foundation-subsoil system, as well as different earthquake input scenarios, in terms of selected ground motion records. For this purpose, a real bridge already constructed in Greece is studied and a parametric analyses scheme is developed for different finite element models of increasing analysis complexity. It is shown that at least for the particular bridge studied, the most critical links in the chain of analysis reliability is the definition of a 'reasonable' earthquake scenario and the appropriate modelling of the abutment-embankment dynamic stiffness.
