A numerical method is presented herein to study soil-pile interaction systems in a stratified media. The method is based on a coupling of the finite element method and the boundary element method. The near field is modeled by the finite elements whereas the far field is modeled by the boundary dement formulation using the multi-layer dynamic fimdamental solution that satisfies the radiation con...

Dynamic analysis of embedded foundations like pile groups have received considerable attention in the past. Most existing approaches are established in the frequency domain, not allowing the simulation of material and geometric nonlinearities. In this paper, transient analyses are conducted to calculate the impedance of piles and pile groups, using a full three-dimensional numerical model for b...

the pile-raft foundation is a combination of a raft foundation with piles. pile-raft foundation has been widely designed, assuming all structure loads to be transferred to piles without considering contribution of the load taken by contact surface between raft and soil. methods of analysis currently used in practice are based upon relatively conservative assumptions of soil behavior or on the l...

Beam on a Nonlinear Winkler Foundation (BNWF) approach is widely used in practice since the simulation process is rather simple and requires less computational efforts compared to three-dimensional continuum modeling approaches. In the recent decades, this approach has been extended by proposing advanced onedimensional models in order to better simulate the soil-pile interaction. In this paper,...
