In practice, the seismic effect of piles are either ignored
or simplified, where the soil-pile-structure interaction is omitted. In this
approach the structure is assumed to be fixed to the foundation and a spectral
analysis is performed in accordance with earthquake regulations. Implicitly the
error in design is assumed to be on the safe side considering the period shift
and increased damping of flexible piled foundations which actually leads to
smaller structural loads when compared to fixed structures. Observed damages in
earthquakes of last fifteen years have shown the importance of analyses taking
into account the soil-pile and structure interaction for pile foundations
designed in earthquake-prone areas. Pile damages in earthquakes, model testing
and back-analysis of piles damaged in seismic activity have led to increased
understanding and appreciation of the mechanism for pile-soil-structure
interaction. In this paper, the mechanism of seismic soil-pile-structure
interaction is explained and numerical analyses suggested in the literature for
seismic pile design are shown. Furthermore, the importance of
soil-pile-structure interaction and the significance of soils are emphasized.
