Response of A 850 KW Wind Turbine Including Soil-Structure Interaction During Seismic Excitation

Conference paper
Part of the Sustainable Civil Infrastructures book series (SUCI)


On-shore wind turbines are typically founded on shallow gravity-based foundations that are designed to transmit vertical and lateral loads. Improved understanding of the foundation, as well as the over-all system behavior will lead to safe and economical designs. In this study, experimental results of a 55 m in-service Gamesa G52/850 wind turbine tower are employed to calibrate a three-dimensional finite element model. The response of a G52/850 wind turbine founded on shallow foundations and subjected to seismic excitation is studied with due consideration of the role of soil-structure interaction. The numerical model accounts for the soil-structure interaction via a pressure dependent multi-yield surface soil constitutive model. The calibrated FE model is then used to investigate the response of the wind turbine under earthquake-like excitation. The fundamental mode shape, the dynamic response as well as the soil-structure interaction effect are reported and evaluated. The investigation provides a valuable insight into the extend that soil-structure interaction influences the behavior of the wind turbine tower under seismic excitation.
