Study on the structure design of quadrangle towerframe steel chimney

Abstract

Abstract:

To understand the deformation of quadrangle framed steel chimney under different loads,a modal analysis was carried out using the finite element program MIDAS. The stress of the frame and chimney should be taken into account at the same time. The mode of the towerframe steel chimney was affected by the opening at bottom, and the stress in the diagonal direction is most unfavorable to the structure. The temperature load has a great influence on the column feet of a hightemperature chimney, and reasonable structural measures must be taken to release the temperature stress. The steel frame should be slidably connected to the cylinder of the chimney on Y direction, releasing the freedom degree and reducing the thermal deformation.
