Abstract

Highlights
•A two-dimensional analysis of a monopile segment moving horizontally through saturated soil is analyzed.
•A p−y−ẏ curve accounting for the rate of pile motion is proposed as an alternative to static p−y curves.
•The stiffness and damping properties related to soil structure interaction are determined by implementing the u-p formulation for the porous media.
