چکیده مقاله
Simplified analytical models are represented for vertical harmonic vibration response of pile soil interaction in layered soil The pile is assumed to be vertical and elastic, the soil is considered as a linear visco elastic layer with hysteretic type damping The layer alone is solved first and the harmonic loading of the layers are used in the analysis of the pile response The pile response to a harmonic load is obtained in a closed form and used to define stiffness and damping for the pile head Parametric studies have been performed to investigate the effect of soil layer thickness and properties A new technique initially developed by the first author has been used for analyses carried out in the current research This segment by segment method SSM is used to determine the response of pile to deal with the soil heterogeneity along the pile shaft It will be shown that the new technique is able to characterize the pile efficiently
