Chimneys are tall structures and the major loads acting on these are self weight of the
structure, wind load, earthquake load & temperature loads. In this paper the structural behaviour of the
40m above height bio medical waste disposal steel chimney in trichy sengipatti has been investigated. This
report summarizes results collected from about 6month of continuous measurement and regular
observations of the chimney. Steel chimneys are designed considering dead load, wind load and earthquake
load.
Geometry of a self supporting steel chimney plays an important role in its structural behavior
under lateral dynamic loading. This is because geometry is primarily responsible for the stiffness
parameters of the chimney. However, basic dimensions of industrial self supporting steel chimney, such as
height, diameter at exit, etc., are generally derived from the associated environmental conditions. To ensure
a desired failure mode design code (IS-6533: 1989 Part 1 and part 2) imposes several criteria on the
geometry of steel chimneys.
