Looking extra deeplywith more depth into this problem, Mylonakis et al .[9], studystudied the role of the interaction of soil structure on the failure of the bridge inon the Hanshin Expressway. The bridge, Buildingbuilding from a single concrete pier with circular section monolithically connected to a concrete deck with 18 spans in total, was founded on groups of 17 piles in different layers of sand (loose to dense) and moderate to stiff clays. It was shown that the augmentation in seismic demand in the piers had override 100% in comparison compared to piers with base fixed bases. From the experimental point of view, there are very few experimental investigations examining the PSSI effects on the seismic responses of integral bridges with pile foundations instill inin site soil, such as cable-stayed bridges. DuringOver the past two decades, there werehave been a large number of shaking table studies focusing on the PSSI effects on the seismic responses of only simplified bridge structures with various sand or soil [10-16],; namely, their superstructures were modelled as a simplified structurestructures.
