Validation of a High Cycle Accumulation Model via FE-Simulations of a Full-Scale Test on a Gravity Base Foundation for Offshore Wind Turbines.

Kurzbeschreibung (Abstract)
Up to now, there is a lack of validated analysis procedures for the determination of accumulated deformations in the subsoil of foundations for offshore wind turbines. This contribution shows first results of such a validation of the High Cycle Accumulation model (HCA) [4],[5]. Basis of this validation are results from a full-scale test on a gravity base foundation subjected to high cyclic loading. The essential simplification of the subsoil, the material parameters and the input parameters for the FE-simulations are shown. The comparison of calculated and measured accumulated settlements of the foundation showed a quite good agreement. Furthermore it is worked out, that the initial relative density plays a significant role for the prediction of the accumulated deformations of the foundation.
