摘要：
Offshore wind turbines (OWTs) are exposed to the combination of cyclic wind and wave load, thus causing fatigue damage to the structure. In this paper, time domain model analysis against fluctuating wind and wave for the large-scale OWT has been done to get the stress time histories for analyzing cumulative numbers of stress ranges. The paper concluded that the structural damage becomes rather significant in case of the OWT around 5000-6000kW clarifying the relation between the first mode natural periods and the fatigue damage ratios for OWTs.
