Numerical Simulation of Pile-Soil-Structure Interaction under Dynamic Loading
In this paper, nonlinear pile-soil-structure interaction under dynamic loads is formulated by using free-field soil analysis and beam on Winkler foundation. The free-field motions are calculated separately through a site response analysis using DYFRA program which was developed by the author to prepare the data in the form of displacement time history. Linear beam column finite elements are used to model the piles and structural elements. Nonlinear modeling of soil media is done by introducing a rational approximation to continuum with nonlinear interface springs along the piles. In order to calibrate the parameters used in the model and also verify the proposed formulation, the result of a shaking table tests are used. The numerical analyses-show good consistency with the test results, in terms of recorded spectral acceleration of soil layers and acceleration time history of superstructures above the piles.
