Seismic Analysis of RC Elevated Water Tank Using Different Staging Pattern

Abstract

The present review explores the performance of a circular water tower by utilizing dynamic analysis (response spectrum technique). The investigation is carryout by considering different parameters like water storage capacity, height of water tower are taken as consistent and variation in, number of segments (Column’s), h/d ratio, staging arrangement such as normal staging, hexagonal staging, cross staging and radial staging with central column are consider here. By considering all this parameter total 36 models for empty tank, half tank and full tank condition are created, All tank are models for the seismic zone III. We have made the used of STAAD.pro software based on finite element method. The response of each water tower with respect to other will be checked for base shear, axial force, bending moment, twisting moment, and lateral displacement. The behavior of water tower is describes with the help of graphs. As the structure is fixed at the base and free at the top so there is an increase in stiffness and there is a change in magnitude of lateral displacement and base shear.
