New method to calculate the kinematic response of offshore pipe piles under seismic S-waves

Libo Chen et al.

Summary: This paper developed an analytical framework to determine the kinematical response factors of open-end offshore pipe piles under seismic S-waves. The vibrating of pile in horizontal direction was characterized by the Timoshenko beam theory. The dynamic soil impedance and hydrodynamic force were calculated based on the porous medium assumption and radiation wave theory. The effects of various factors on the kinematic response and deformation performance of offshore pipe piles were discussed in a parametric study.

Analytical solution for horizontal vibration of end-bearing single pile in radially heterogeneous saturated soil

Chunyi Cui et al.

Summary: An analytical model for the horizontal vibration of a single pile embedded in radially heterogeneous saturated soil is established using Biot's dynamic equations and Novak's thin-layer theory. The frequency-domain response of the surrounding soil and the analytical solution for the horizontal impedance of pile head are derived. The accuracy of the obtained solution is validated through independent comparisons, and the effect of soil radial heterogeneity on the horizontal vibration of an end bearing pile is discussed through extensive parametric analysis.

Kinematic response of end-bearing piles in saturated soil to seismic SH-waves

Changjie Zheng et al.

Summary: This paper presents a mathematical model for the seismic analysis of end-bearing piles in a finite thickness homogeneous saturated soil. The seismic loading is modelled as harmonic horizontal strong motion of the rigid bedrock, generating vertically-propagating shear SH-waves. The model takes into account the energy dissipation due to relative movement between the pore fluid and the solid matrix, which affects the amplitude of high-frequency components of the strong motion and the kinematic response of the piles. The paper also identifies the soil permeability threshold for reliable results using simpler single-phase soil models.

Dynamic response of floating piles subjected to axial loads considering three-dimensional soil deformations

Changjie Zheng et al.

Summary: This paper presents a systematic study on the effect of radial soil deformations on the dynamic response of floating piles subjected to axial loads. The proposed novel mathematical model is compared to rigorous numerical boundary integral methods, and it is shown that the model produces similar results. Comparisons with an earlier model show that the confined model overestimates stiffness and underestimates damping of the pile impedance in the low frequency range, regardless of the problem conditions.

Vertical dynamic response of single floating piles in poroelastic soil

Changjie Zheng et al.

Summary: This paper presents a closed-form formulation for the time-harmonic response of single floating piles embedded in a saturated soil layer. The frictional force of surrounding soil to pile vertical motion is established considering the soil layer as a homogeneous isotropic poroelastic medium. The closed-form solution is obtained from the boundary and continuity conditions, avoiding the need for numerically solving complicated integral equations.

Dynamic response of pile embedded in unsaturated soil under SH waves considering effect of superstructure

Zijian Yang et al.

Summary: In previous soil-pile dynamic studies, the effects of air in soil pores and the influence of superstructures on the seismic performance of piles were often neglected. This study establishes a novel model to investigate the seismic performance of piles under the influence of superstructures. Analytical solutions are derived and verified through comparisons with previous studies. The study concludes that soil water saturation, superstructure mass, and the vibration of the free-field soil significantly affect the system's seismic response.

Analytical solution for lateral dynamic response of pile foundation embedded in unsaturated soil

Xiaoyan Yang et al.

Summary: This paper establishes a coupled dynamic unsaturated soil-pile interaction model and derives the analytical solution of the pile dynamic impedance using an analytical method. The study reveals that an increase in soil saturation leads to a decrease in soil strength, resulting in increased pile displacements and internal forces. Both increased soil permeability and decreased soil saturation decrease the pore pressure at the side of the pile, with smaller saturations causing greater matrix suction. The natural frequency of the pile decreases with increasing soil saturation.

Closed-form formulation of vertical dynamic response of single floating piles in homogeneous viscoelastic soil

Changjie Zheng et al.

Summary: This paper presents a mathematical model for the elastic analysis of single floating piles subjected to axial dynamic loads. The model treats the soil surrounding the pile as a viscoelastic continuum and uses one-dimensional rod theory to model the pile and the soil column underlying the pile tip. The model provides closed-form expressions for the dynamic stiffness at the pile head and the frictional resistance along the pile shaft. The paper concludes with a discussion on the main mechanisms governing the inertial response of floating piles and investigates the sensitivity of the dynamic stiffness and frictional resistance to geometric and material parameters.
