Seismic Analysis of Conventional, Braced, and Shell, Elevated Water Tanks for Different Seismic Zones

Abstract

Abstract: Water is stored in the tanks and then distributed through the public water supply systems. The term "overhead water tanks" (OWT) or "elevated water tanks" (EWT) refers to water tanks that are constructed at a specific height. A large mass that is concentrated at the top of the EWT is supported by thin supports. The horizontal stresses brought on by earthquakes affect it severely. The elevated water tanks all around the world either collapsed or experienced major damage as a result of the earthquake since the supporting mechanisms were either poorly constructed or selected. Different structural methods and materials have been employed by a number of researchers and designers to create safe designs that keep the EWT stable during earthquakes. The current study's objective is to analyze the conventional, braced (diagonal and cross), and shell-stagging EWT for seismic zones III and IV. For that purpose, the lateral displacement and base shear of conventional, braced (diagonal and cross), and shell-stagging elevated Intze tanks have been investigated and compared. The current study also illustrates how zones III and IV are affected by full and empty EWT situations. The shell EWT has performed better than conventional EWT when lateral displacement and base shear are compared.
