65m高钢制排气筒消除横风向风振分析

The Elimination of Across-wind Dynamic Vibration for the Steel Exhaust Funnel with height 65 meter

报道65m高钢制排气筒发生以及消除横风向风振的实例,对照有关标准对原设计进行分析,说明设计缺陷同发生横风向风振存在因果关系,总结发生及消除横风向风振的经验教训,为自立式钢烟囱的建造提供一个可供参考的案例。

This paper indicates a real example of elimination of across﹣wind dynamic vibration for steel exhaust funnel with its height of 65 m. It also analyzes the original design according to the related industry standard,and explain the causal relationship between fault design and across﹣wind dynamic vibration so as to generalize the reasons for such issue and the method for the further elimination,generating the reference of building the self﹣supporting steel chimney.
