[en] This chapter presents a study on the behavior of monopiles for offshore wind turbines
under lateral loading, with a special focus on monopiles grounded in clayey soils.
The behavior of the monopile is studied in terms of soil reaction curve. The analysis
focuses on three main points: under monotonic loading, we have analyzed the effect
of the loading velocity on the response of the foundation. Simulations have clearly
shown the influence of loading velocity on the behavior at the soil-pile interface. Then,
based on an anisotropic constitutive law, the influence of both types of anisotropy
(initial and induced by loading) has been studied. Finally, we have considered a nonalternating
cyclic loading, in order to analyze the effect of cyclical accumulation on
force-displacement curves of monopiles.
