“…The substructure method was used to develop 3D FEM-BEM based models in order to investigate the vertical and lateral dynamic response of piled raft systems for various soil profiles. It was observed that dynamic load distribution between pile and raft for 2x2 piled rafts, was frequency dependent in the vertical mode and frequency independent in the lateral mode [21]. In another study, the effect of SSI and spatial variations in ground motion were investigated for cablestayed bridges.…”

“…Moghaddasi et al [30] presented a hybrid analytical-numerical method for the dynamic analysis of piles and pile groups embedded in nonhomogeneous transversely isotropic media subjected to lateral excitations, in which the piles are simulated using finite elements and the interactions between piles and soil are captured through a system of rigid, massless elements. Varghese et al [31] proposed a substructure-method-based soil-structure interaction analysis model to study the vertical and horizontal dynamic impedances of piled rafts in homogeneous and layered soil conditions. Wang and Ai [32] developed a method to compute the dynamic response of pile groups in layered soils with compressible constituents by combining the analytical layer element method and finite element method.…”

“…Pile foundations are commonly adopted to support structures in civil, coastal and offshore engineering, etc. Longitudinal vibration of piled structures due to vertical ground motion of earthquake, traffic and vibrating machinery is of great practical engineering significance for dynamic foundation design, earthquake-resistance design and pile dynamic testing [1][2][3]. Hence, the studies of *Manuscript Click here to view linked References longitudinal vibration of pile have attracted extensive attention in recent decades [4][5][6].…”
