[Abstract]
Regarding the seismic analysis of wind turbines,this paper presents and discusses relevant studies worldwide during the past two decades from the following four aspects:frequency domain analysis based on seismic response spectrum,highfidelity finite element analysis of structural dynamics,dynamic analysis approach with coupling of wind and earthquake,and structural control against earthquakes.The developments and the characteristics of these numerical methods are discussed.The limitations and insufficiencies of current researches are analyzed.Based on the state of the art of seismic analysis for wind turbines,the future research and development direction are recommended.
