Seismic behaviour of piles in non-liquefiable and liquefiable soil

Abstract: This paper investigates the nonlinear soil-pile-structure interaction (SPSI) employing three-dimensional (3D) nonlinear finite element (FE) models verified with the results of large-scale shaking table tests of model pile groups-superstructure systems.The responses of piles in both liquefiable and non-liquefiable soil sites to ground motion with varying intensities were evaluated considering both kinematic and inertial interaction. The calculated piles and soil responses agreed well with the responses measured… Show more

“…In contrast, the amplification of acceleration increased in the non-liquefiable site. Hussein and El Naggar (Hussein & El Naggar, 2022) developed 3D FE simulations to research the seismic response of the SPSI used in the shake-table tests to assess the influences of various pile and soil parameters (Xu et al, 2020). Their research investigated both influences of kinematic and inertial forces on the pile group in the liquefiable and non-liquefiable soil.…”

“…Analytical studies [21,22] have been performed to determine the influence of soil-pile-structure interaction in liquefiable soils and the influence of relative density and the position of a liquefiable soil layer on the buckling capacity of pile foundations. The behavior of a pile foundation depends on the structure mass, pile stiffness, soil density, acceleration of input motion, and slope of the ground [23]. The pile bending moment is maximal when the liquefiable soil deposit is 60% of the non-liquefiable soil layer.…”

“…Liquefaction issues are addressed by Hussein and El Naggar (2021), who investigate the seismic behaviour of piles in non-liquefiable and liquefiable soil through nonlinear soilpile-structure three-dimensional numerical models, verified with the results of large-scale shaking table tests. Ground motions with varying intensities are considered and both kinematic and inertial interactions are addressed in their study that, for technical reasons, was published in a regular issue although candidate by the Authors for the inclusion in this collection.…”
