jce.7.4.13802 Seismic Stability of Pure Conical Elevated Water Tanks under Varying Tank Inclination S.S. Quadri R.M. Sawant Journal on Civil Engineering 2249-0779 7 4 43 59 10.26634/jce.7.4.13802 Pure Conical Tank, Tank Inclination (q), Finite Element Models, Response Spectrum Method Pure conical elevated water tanks are widely used as water reservoirs in various locations around the world. Current Indian codes of practice do not provide any provisions or guidelines for the analysis and design of reinforced concrete pure conical elevated water tanks under hydrostatic loading. Available code provisions are limited only for the design of cylindrical and rectangular tanks. In this paper, a Finite Element Model (FEM) of pure conical elevated water tank is made by using a structural analysis and design computer program, i.e. STAAD.Pro. The current study focus on the behavior of pure conical elevated water tanks under varying tank inclination (θ) for a constant volume of 500 cubic meter. The aim of this research paper is to find out the optimum angle of inclination (θ) for the conical tank by performingDynamic analysis, i.e. using response spectrum method. The inclination (θ) of the conical tank is increased at a rate of 5o and varies from 15o to 80o are considered in the analysis. The entire tanks are model for the seismic zone-V as per IS-1893-2002. The Response of each conical tank with respect to others will be checked for Base Shear, Principal stresses, Hoop Stresses, Meridional Stresses, Bending Moment in plates, for conical portion and Shaft portion, Bending Moments in ring Beam, and Lateral displacement. The behavior of each conical tank with respect to others is shown with the help of graphs for Empty tank and Full tank condition. September - November 2017 Copyright © 2017 i-manager publications.
