Steel chimneys are utilized all over the world for quick work in industries and for discharging flue gases into nature. Where chimneys are utilized, the nearby region is not influenced by the chimney gases because the chimney height is set high.This paper focuses on frequency analysis of steel chimneys for 275m and 120 m heights. Two models of each chimney are considered, Model 1 tapered section with uniform thickness and Model 2 uniform diameter and thickness are considered. Finite element method (FEM) is used for extracting the first thirty frequencies in chimney. Finite element software ANSYS is used for frequency extraction. The effects of height to diameter of chimney, tapered and uniform cross-section on frequency of chimney are investigated.
