Analysis of Self Supported Steel Chimney
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
From the last few decades the construction of tall stacks increases due to increase in air pollution. Here in this paper, the “Self supporting steel chimney” of height 60m was considered and analysed for the prevailing wind forces and seismic forces considering chimney in four different earthquake zones and bending moments, shear forces were calculated using IS 6533 (part1&2):1989 and were also plotted. Also the chimney was modelled using STAAD PRO Vi8 software. And in the next part, is to justify the code criteria with regard to basic dimensions of industrial steel chimney. A total of 66 numbers self supporting steel flared unlined chimneys with different top-to-base diameter ratio and height-to-base diameter ratio were considered for this study. The thickness of the chimney was kept constant for all the cases. Maximum bending moments and stresses for all the chimneys were calculated for wind load using MS- Excel sheets and were plotted as a function of top-to-base diameter ratio and height-to-base diameter ratio.
