摘　　要：圆截面高耸结构易引起涡振,本文通过对某80m钢烟囱考虑涡振的设计,指出钢烟囱结构设计的关键是对其固有频率的控制,利用有限元软件ANSYS对不同体形钢烟囱进行分析,并与规范公式计算结果比较,为今后的分析和设计提供了参考。Because of wind force, vortex vibration is easily occurred in high-rise Structures which are circular section. In this paper, an 80m steel chimney is designed, vortex vibration is considered. Structure frequency control is consider to be the key factor in steel chimney design, general finite element analysis software is employed to steel chimney design, results from FEM and formula in standard are compared, several design advice for similar structures are given. It provides a reference for chimney analyzing and design.
