Wind Vibration Analysis of a 80m Tall Steel Chimney
Wn Dechao et al.
In this paper, the vibration problem of a chimney is studied from the aspects of chimney frequencies, wind vibration frequencies and Reynolds number. The chimney frequencies were calculated by many methods, such as FEM and simplified method. The error between the fundamental frequency calculated and the measured value is less than 5 % . The resonance domain with wind and the reasons of vibration were found. A simplified formula for calculating the fundamental frequency of chimney is modified. Concrete measures to mitigate the vibration of the chimney are presented.
