Response of Piles during Earthquakes: Dynamic Soil-Pile-Superstructure Interaction
The dynamic response of pile foundations in soft clay and liquefiable sand during strong earthquake shaking was evaluated. The research consisted of two major components: (1) a series of dynamic centrifuge tests of pile-supported structures in soft clay and liquefiable sand; and (2) an evaluation of dynamic 'beam on a nonlinear Winkler foundation' (BNWF) analysis methods against the centrifuge model results. Several BNWF computer programs were shown to give consistent results for similar idealizations of a physical problem. Two men p-y elements were implemented into the program GeoFEAP. The representation of radiation damping was shown to be important in certain cases, with series radiation damping being technically preferred over parallel radiation damping in such cases. Calculated responses for a single pile in soft clay were in good agreement with the centrifuge data when using series radiation damping and a p-y element with gapping ability.
