SEISMIC ANALYSIS OF RCC CHIMNEY AND ITS INTERACTION CHARTS
Graduate student at Dept. of civil engineering, Sigma institute of engineering-Vadodara, India
ABSTRACT
Most of the industrial RCC chimneys are tall structures with circular cross-sections. Industrial Chimneys are generally intended to support critical loads produced by seismic activity and Wind. So it is essential to evaluate the dynamic response of chimney to seismic activity & response to Earthquake is more critical as chimney is a slender structure. In the design of tall chimneys, estimation of exact earthquake is very difficult. Empirical as well as analytical approach proposed by different researchers for the estimation of earthquake response of a chimney doesn’t give satisfactory results. Parametric study on chimney from height 150m & 200m.Our aim is to predict earthquake response of tall chimneys of different height and diameter with analytical approach taken as per IS 4998-1992 (PART I) and compare with corresponding experimental values. Interaction charts due to loads, soil and location will be prepared.
