Abstract: Chimneys are tall structures and the major loads acting on these are self weight of the structure, wind load, live load due to lining, earthquake load & temperature loads. In this paper a RC chimneys will be designed considering dead load, wind load and earthquake load. The Bureau of Indian Standards (BIS) design codes procedures will be used for the design of chimney. The present paper discusses the parametric study of RC chimney which is made by obtaining the results from software for different heights, diameter, earthquake zones, wind zones, type of soils and various load conditions because of changes in the dimensions of chimney, structural analysis such as response to earthquake and wind oscillations have become more critical to influence on the response and design of chimney. Parametric study on chimney from height 150 meters to 250 meters at an interval of 5 meters, for Zone II, Hard soil & Critical Zone of Zone V, Soft soil with wind speed varying from 33 meters/sec to 55 meters/sec with an internal temperature of 100 Degrees. The response of the chimney is studied & recorded in Tables & Graphs. The analysis is carried out using programming software Microsoft Visual Basic 6.0. The results obtained from the above cases are compared. Finally, the maximum values obtained in wind analysis and seismic analyses are then compared for deciding the design value.
