Dynamic analysis of rectangular tank using response spectra

Abstract

Reinforced concrete tanks are currently used to store various substances and products. Most often they serve as drinking water reservoirs, to sewage treatment or to store various technical fluids. Although rectangular tanks are less used, they have advantages, such as less sensitivity to one-sided loading and better utilization of space when using a group of tanks. Rectangular tank which is the matter of interest in this paper is for the purposes of analysis considered as fulfilled with water. Dynamic analysis of the tank considering fluid-structure interaction (FSI) was the matter of interest here. Deformations and bending moments of walls were obtained.
