摘要：
Based on the probability distributions of wind direction and wave direction, the fatigue load is applied to the offshore wind turbine structure according to the actual environmental loading direction. The deterministic fatigue damage due to the wind load and the spectrum fatigue damage due to the wave load are calculated, respectively. Then, the total fatigue damage of the offshore wind turbine structure is obtained by the linear superposition. Compared with the results that the fatigue damage of the offshore wind turbine structure is computed under fatigue loads exerted in single direction, the results of omnidirectional fatigue analysis are more reasonable.
