Abstract:

This paper analyzes the stress distribution at the opening of a 60-meter-high self-supporting steel chimney under specific loads by using the finite element software ANSYS. The results show that the weak position simulated by the software is consistent with that calculated by the chimney design code. When the calculated stress-strain level at the chimney opening is low, the wall thickness at the opening can be appropriately reduced or the steel section can be reduced to improve the stress level. When the tube wall of the opening is plastic, the wall thickness at the opening or the section steel can be increased, and the wall thickness of the nozzle can be increased to reduce the stress level and make the tube wall of the opening within the yield strength.
