Abstract: In this paper，according to the characteristics of the wind loads acting on angle-steel communication tower，the fluctuating wind will be considered as a stable Gaussian random process. Based on stochastic theory and the spatial correlation is considered，the time-history curve of fluctuating wind load is simulated using harmonic synthesis method and Matlab language，so the computer simulation of fluctuating wind is realized. The theory and procedure of the simulated time-history curve，could be applied to the simulation of fluctuating wind load of the general high-rise structures，and the general statistical characteristics conformed with the stochastic process of wind speed have a good randomness. Finally an angle-steel communication tower as engineering background，and establish accurate finite element model，then the dynamic characteristics and wind-induced response of the steel tower are calculated using ANSYS transient dynamic analysis modules. Then a research is made on the coefficient value response of wind-induced vibration response of angel-steel communication tower.
