Abstract
In this paper, the dynamic response of pile groups embedded in 3-D homogeneous transversely isotropic media subjected to time-harmonic vertical and horizontal loading is investigated. The response of pile groups is calculated by a novel method. This method is less complicated than boundary elements method (BEM) used in the most previous studies in this field. In the method the pile groups is discretized to some beam-column elements and radiation discs. The radiation discs represent the propagation of wave from piles to the unbounded soil medium. By calculating the dynamic stiffness of radiation discs and setting with beam-column elements, the dynamic stiffness of pile groups embedded in soil is properly determined. In this paper, the response of the transversely isotropic 3-D half-space subjected to time-harmonic vertical and horizontal excitations is presented in analytical form.
