“…Often the fracture or stretching of bolts, or the stripping or loosening of nuts, is the first visible sign that there is a fatigue problem caused by vibration. Any occurrence of a failure of several bolts in a chimney should prompt an investigation of vibration [3,12]. Vortex suppression devices such as shrouds, helical strakes, spoiling plates and vertical vanes or damping devices should be fitted to stack to minimize the VIVs and to increase fatigue life [5,13,14].…”

As vibrations from vortex-shedding occur at moderate wind speeds, structures undergo a considerable number of stress variations. So risk of fatigue is to be taken into account at the design stage itself. Even if a fatigue analysis is not demanded in the code to be applied, risk of fatigue is to be considered, especially with regard to slender steel chimneys due to larger volumes of material subjected to high stresses. Thus, risk of fatigue which has not been addressed in the Indian context, has been taken care in the present paper. It is envisaged that this formulation will be appropriate for inclusion in Indian codes and standards. As part of the case study, a chimney from an industry having Diesel Power Plant has been undertaken. Fatigue analysis of this chimney has been done and measures to reduce fatigue problem have been suggested.

“…With the collected behavior data, fatigue calculations were made based on the Eurocode and were compared with the constant amplitude method. Tranvik and Alpsten [81] investigated the structural behavior of a 90 m high steel chimney and summarized the results collected from approximately four years of continuous measurements and regular observations of the chimney. The obtained data have some general relevance with respect to wind data, behavior of a slender structure under wind loading, and the effects of a mechanical damper.…”

First of all, I owed much of my graduate work to my wife, Hyesun Cheong, for her endless love and assistance. This appreciation should be extended to my sons, Eugene Chang and Justin Chang, for that they grows up very well without any significant problems during my study. The successful completion of this dissertation and the research discussed herein would not have been possible without the guidance and support of my graduate advisors, Dr. Brent M.
