Abstract：To study a dynamic characteristics for transmission tower under the typhoon wind field, in the example of transmission tower in Guangdong in this paper, the samples of fluctuating wind speed have been numerically simulated by the harmonic wave superimposing method, by using of Shiyuan typhoon wind speed spectrum which is unchangeable with the height. And the FFT technique is adopted, so the simulation can be easy and efficiently performed. By comparing the auto power spectrum and the cross power spectrum, it is found that the values of the simulated wind field agree well with the target values. So it is proved that the method presented in this paper is valid and reliable.
