Abstract
With the construction of extra high voltage grid
the span of wind vibration coefficient of transmission towers has become an important topic recently.Based on fluctuate wind simulation and structures stochastic vibration
wind-induced vibration response of transmission tower is analysed by the method combined MATLAB and the second development of ANSYS.The calculation of wind vibration coefficient is proposed in the paper and can provide reference to electric project.
