Abstract
In last three decades, the constructions of tall stacks were prominent to prevent and control air pollution with the growing interest of industrial development. These structures are generally slender, and tall with cylindrical and circular cross-sections. The constructions of chimneys in practice are with different support conditions such as self-supported, guy wire etc. The most frequent construction materials for chimney or stacks are concrete, steel and masonry. This paper presents the analysis and design of Guy Supported industrial steel chimneys comprises a number of sets of collars (guy wire arrangement) and various height to diameter ratios such as 25, 29 and 33 (the most preferable ratios as per IS 6533 (Part 1): 1989), The analysis were carried out by using STAAD software considering various loads such as dead load, temperature effects, wind, seismic loads etc. and combination of it. As lateral loads are dominant the considered basic wind speeds are 39m/s, 47 m/s, and 55m/s (as per IS 875 (Part 3): 1987) and Seismic load are taken as per IS 1893 (Part 4): 2005 for particular work considering seismic zone-II and with medium soil.
