Abstract

Comparisons between an Euler modelled large diameter pipe pile and a Timoshenko modelled large diameter pipe pile are developed to obtain the steady-state response of horizontally loaded pipe pile embedded in a homogeneous soil and resting on a rigid base. In the analysis, the soil is simulated as an axisymmetric linear viscoelastic continuum and the pile is modelled as an elastic Euler rod and Timoshenko beam, respectively. In the process of comparative studies, second-order effects of vertical loads applied on the pile head are considered and the soil surrounded in the pipe pile is also taken into account. Based on the existing analytical solution, comparisons between the Euler model and Timoshenko model are performed to investigate effects of shear deformation and inertia, second-order effect, and inner soil on horizontal dynamic response of the large-diameter pipe pile. Furtherly, the plots developed from the parametric study can provide reference for engineering application.
