Özet

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.
