Uncouple Nonlinear Modeling of Seismic Soil-Pile-Superstructure Interaction in Soft Clay

This paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experimental data of large-scale seismic soil-pile-structure tests which were conducted on shaking table in uc berkeley. a comparative evaluation of single piles shows that the results obtained from the proposed procedure are in good agreement with the experimental results.
