<p>This study examines the structural responses of a novel articulated foundation wind turbine with compliant structural design under offshore winds, waves, and seismic events. A numerical simulation analysis framework, ADRT (Articulated Foundation Offshore Wind Turbine Dynamic Analysis and Response Prediction Tool), has been developed and validated through benchmark studies with established numerical tools, demonstrating strong correlation. The research conducts dynamic response analysis of the Articulated Foundation Offshore Wind Turbine (AFOWT) system under various seismic scenarios. Analysis reveals that response amplitude increases proportionally with seismic intensity. When wind and seismic forces act simultaneously, the system’s response amplitude perpendicular to the rotor plane decreases compared with isolated seismic action, attributed to aerodynamic damping effects, except for blade deformation response. During emergency braking shutdown operations triggered by seismic excitation, the structural seismic response exceeds design safety thresholds during the shutdown feathering process, indicating that emergency shutdown procedures do not effectively mitigate the system’s structural response.</p>
