heal.abstract	During an earthquake event, seismic oscilation might be accompanied by large surface soil movement, due to the outcrop of the causative fault. This fault rupture has proved to have had disastrous effects on several structures it came across during past earthquakes. Yet, there have also been cases reported, where the structure has survived this encounter, almost intact. In this project, the response of a typical overpass bridge subjected to dip-slip faulting is examined. The bridge under examination has two spans and its mid-pier is founded on an isolated footing. A 2D finite element parametric analysis is being carried out, in the first place, taking only the footing into consideration, in order to comprehend the various ways in which the system interacts, based on its geometry. As it turns out, the exact location of the foundation relative to the fault is a key factor to the interplay of the soil-foundation system. Further on, the most characteristic results of the above step are being compared with results derived from an equivalent 3D model. Eventually, the bridge’s superstructure is added to the 3D model, in order to investigate its impact on the response of the whole system. The results point out that when examining problems of this type, it is essential that the whole structure is modelled, because not only it modifies the way the other components behave, but also because the superstructure itself might suffer substantial damage. Finally, a small-scale (1-g) experiment for reverse faulting in the free field is conducted in the Soil Mechanics Laboratory of NTUA, in order to re-validate the numerical methodology employed, but also to calibrate a newly introduced to the Laboratory type of soil.	en
