Impact of revised code provisions of seismic and wind loads on RCC elevated water tanks

Abstract

Reinforced concrete elevated water tanks have been reckoned as importance structure for post-earthquake and Post cyclonic emergency service consideration.Certain additional guidelines have been recommended in IS 1893 (Part-2) 2014 Earthquake code and IS 875 (Part-3) 2015Wind load code in cyclonic prone areas of Indian peninsula. Three different capacities of RCC Elevated water tanks have been examined the effects of revised code provisions with the STAAD Pro (v8i) software to assess the internal parameters such as axial force at the ground level, Bending moment, Base Shear force and finally the quantity of steel required. The effect of Zonal classifications is illustrated and finally it can be concluded that the Earthquake design criteria governs when compared to Cyclonic load.
