Abstract

This chapter presents a study on the behaviour of monopiles for offshore wind turbines under lateral loading, with a special focus on monopiles grounded in clayey soils. It considers a one-way cyclic loading in order to analyze the effect of cyclical accumulation on force- displacement curves of monopiles. The chapter is based on an anisotropic constitutive law, the influence of both types of anisotropy has been studied. It dedicates to the numerical analysis of the monopile. The chapter discusses two cases of monotonic and cyclic lateral loading in order to study the effect of different aspects of soil behaviour in p-y reaction curves. Two-dimensional modeling in the plane deformation state is then only valid for the second failure mechanism. Pile monotonic loading is controlled in displacement. It consists of applying a lateral displacement to the section of the pile with a constant rate of up to 10% of the diameter of the pile.
