摘要
本文对武汉电视塔主体结构的动力特性及抗风可靠性进行了初步分析,用极值分布交换法对武汉地区风荷载进行了统计、动力特性实测及分析和基于泊松假定并考虑风向影响的动力可靠性分析。按本文方法计算的动力可靠性与数值模拟法的计算结果是一致的。
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.
