| Abstract: | This paper presents the dynamic characteristics and wind-resistant reliability analysisof the main structure of Wuhan T.V.tower,including the wind load statistics of Wuhan region byuse of the transfomation method of extreme distribution,the results of dynamic characterisitics anddynamic reliability based on that the time of a threshold crossing is a Poisson process and the effect of wind direction on dynamic reliability is considered.The result shows that the dynamic reliability ofWuhan T.V.Tower determined by the method presented in this paper is in close agreement with thatof Monte Carlo method. |
