Analysis of Response of the Monopile Foundations of Offshore Wind Turbines
The bearing structure of wind turbines in offshore environments is composed of two domains, the steel superstructure and its steel hollow pile foundation which transfers pressures to the soil. The interaction between these domains is of great importance for the dynamic behaviour of the wind turbines. Nevertheless, usual design considerations assume solid pile section of equivalent material properties affecting the accuracy of their analysis. Thus, this study aims at comparing the response of simplified (more efficient from the computational point or view) and complete numerical models, including all the actual geometrical features, under both static and dynamic conditions. In view of this development, detailed Finite Element Method (FEM) models are created within ANSYS, emphasising in the soil-structure interaction effect. For this purpose, material and geometrical nonlinearities are considered into the models. Herein, comparative results of the pile-foundation response of the actual geometry with state-of-practice solutions are presented for both static loadings and dynamic excitations.
