Abstract

The seismic analysis and soil structure interaction module is developed based on FAST v7, forming an aero-hydro-seismic-servo-soil structure coupled simulation software FAST-S, and the calculation accuracy and reliability of the seismic analysis module is verified by Seismic and ABAQUS. Based on the extended software FAST-S, a 5MW monopile offshore wind turbine model considering SSI effect is established to analyze the coupling effect among wind, wave and earthquake, and to study the influence of the near-field ground motion velocity pulse on the dynamic response of the wind turbine support structure under parked and operational states. The results show that the earthquake intensifies the tower top vibration, and the wind-wave load plays a certain role in reducing the tower top vibration induced by the earthquake. There is a nonlinear coupling relationship among aerodynamic, hydrodynamic and seismic loadings, and the wind-wave-earthquake coupling effect should be fully considered in the calculation. Near-field ground motion velocity pulse will increase the tower top displacement, tower top acceleration and bending moment at the mudline of the wind turbine under parked and operational states. In the structure design, attention should be paid to the adverse effects of pulse-type ground motions on the structure, especially the structural safety of the wind turbine under the parked state.
