THE EFFECT OF LOADING FREQUENCY ON SOIL-PILEINTERACTION USING NONLINEAR THREE-DIMENSIONALANALYSES

In this paper, the dynamic response of the soil-pile system was investigated through a set of fullynonlinear three-dimensional numerical analyses in the time domain conducted using the FLAC۳Dprogram. This model simulated soil strength and stiffness dependency on stress level and soilnonlinear behavior under earthquake loading. In the framework of a parametric study, the effects ofloading frequency on the response of the soil-pile system with different soil properties and pilecharacteristics subjected to harmonic loading with specified cycles were studied. The results showedthat pile response including bending moment along the pile length is strongly affected by thefrequency of the seismic load.
