Dynamic Analysis of Elevated Water Tanks

Abstract

Water tanks are very important components of lifeline. They are vital component in municipal water system, firefighting systems and in many industrial facilities for storage of water. The water tanks get heavily damaged or collapsed during earthquake due to the fluid-structure interactions; hence the seismic be-havior of tanks has the characteristics of complex phenomena. Water storage tanks ought to stay practical within the post-earthquake amount to confirm potable water system to earthquake affected regions. The para-metric study suggests that the elevated circular tanks performs better than elevated rectangular tanks. In the present study, a dynamic analysis of elevated RCC water tanks design for the zone III and zone V as per Indi-an Standard: 1893-2002 (Part-2) and analyzed manually as well as using the software considering all the earthquake forces. Objective of this paper is to understand the dynamic behavior of elevated water tanks un-der earthquake loading.
