Study on Seismic Dynamic Response of Offshore Wind Turbine Tower with Monopile Foundation Based on M Method
Making sure the safety of wind turbine tower structure in service is particularly important with the development of offshore wind turbine facility. In order to make mechanical characteristics of structure explicit, dynamic responses of structure under three different types of seismic waves were analyzed by m method and considering monopile-soil-structure interaction, then comparison with the situation when structure was consolidated in the bottom was made. The result shows, dynamic response was most obvious under the action of far-field seismic wave in such high-rise structure as wind turbine tower. When the acceleration peak of far-field seismic wave was in the level of 8-degree rare earthquake, structure would be unsafe with an oversize displacement at the top of tower. Compared with structure consolidated in the bottom, dynamic response of structure was effected by the intensity and stiffness of soil around the pile. The interaction of soil and foundation was needed to be considered in the analysis of dynamic response.
