摘要：

The offshore wind turbines with large-scale bucket foundation is installed in sea area of Qidong city, Jiangsu province of China. Wind tower is high-rise structure, he study on dynamic characteristics of tower structure is very important. The acceleration time interval curve can be obtained under the condition of artificial excitation and natural wind through installing accelerometers, charge amplifiers, data acquisition instrument and so on, on bucket foundation and tower tube. The natural frequency of the tower can be obtained through low-pass filter analysis and Fourier transformation to the acceleration time interval curves. After analysis, the natural frequency of the tower is between 0.3 similar to 0.4Hz. Through analysis on the acceleration time interval curve under the wind force function whether under working condition or shut-down condition, import information on the wind-induced response of the structure can be obtained.
