DYNAMIC RESPONSE OF ۳X۳ PILE GROUPS WITHIN THESOIL-PILE-STRUCTURE SYSTEM USING NON-LINEARTHREE-DIMENSIONAL NUMERICAL ANALYSIS

In this paper, the response of a pile group in a soil-pile-structure system to seismic loading wasinvestigated using fully nonlinear three-dimensional analyses in the time domain. The complete soilpile-structure system was simulated using the direct method finite difference program, FLAC۳D. Thisstudy considers the nonlinear behavior of soil under harmonic loading. Parametric studies wereconducted to investigate the impact of pile diameter, pile length, soil properties, and superstructuregeometry on the seismic behavior of piles. The results showed that pile and superstructure geometricalparameters and soil stiffness strongly affect the soil-pile-structure system's seismic behavior.
