Abstract
A great potential for optimization of pile and bucket-based multi-footed foundations is the adequate incorporation of the non-linear foundation response in the overall structural model of the offshore wind energy converter (OWEC). Currently, this soil-structure interaction problem is treated by a costly and time-consuming iterative procedure between the geotechnical and the structural model. The paper presents a more sophisticated approach which makes the iterative procedure dispensable. Basic idea is to pre-define foundation responses for arbitrary loading conditions by less than twenty load-controlled numerical simulations. The foundation responses are implemented as non-linear macro-elements in the structural model enabling the incorporation of the soil-structure interaction in the equilibrium iteration of the structural model. The basic principle of the proposed approach can be used for all design purposes, i.e. ultimate limit state (ULS), serviceability limit state (SLS) and fatigue limit state (FLS) design.
