Abstract
Monopiles are currently the preferred foundation concept for Offshore Wind Energy Converters (OWECs) in water depths up to 30 meters. These large diameter steel piles have to withstand dynamic wind and wave loading. The stiffness of the monopile-soil system is decisive with respect to dynamic as well as quasi-static loading conditions. To evaluate the stiffness of the monopile-soil system in dependence of the acting load level, a three-dimensional numerical model is implemented which is able to account for a strain-dependent stiffness formulation. Results for a reference system are presented in detail. Furthermore the numerical model is validated on field tests. In a comprehensive study, the main influence parameters on monopile stiffness as the pile dimensions, loading conditions and relative density of soil are investigated systematically. Finally, a comparison of the numerical results with different approaches based on the p-y method is given. It can be shown that the existing approaches are valid only for special loading conditions.
