Analysis of Cantilever Reinforced Concrete Chimney with Variation in Geometry

Any structure needs to be withstanding for two issues, strength and stability. Structure requires a support system that has sufficient strength to bear loads and stability to transmit it safely to the ground. The paper shows the analysis of cantilever reinforced concrete chimney subjected to lateral loads like earthquake and wind loads by considering the variation in geometry. The previous investigations concluded that, height to diameter ratio and thickness of concrete shell are able to resist maximum part of lateral load on reinforced concrete chimney. The scope of present work is to analysis of cantilever reinforced concrete chimney with different height to base diameter ratio and top to base diameter ratio. The equivalent static analysis has been carried out by using STAD-PRO Software and maximum moment and stress calculated as per procedure given in IS 4998 (part -1)-1992. The models where examined for parameters like shear force, bending moment, bending stress, deflection and modal oscillation. The behaviour of reinforced concrete chimney will examine in this experimental work by analyzing it. In this experimental case we are going to assume the different base and top diameter and thickness of concrete shell maintaining the same height of reinforced concrete chimney. Based on the results analysis, the best reinforced concrete chimney is suggested for such consideration.
