Study the fluid structure interaction due to dynamic response of elevated concrete water tank

Research output: Contribution to journalArticle

Abstract

Fluid structure interaction (FSI) is complicated phenomena in which researches trying to suggest new techniques to account its effects in elevated concrete water tanks. Rectangular and circular shapes of elevated tanks have been chosen to conduct this study. In this paper the adding of impulsive mass to elevated tank has been modified instead to Westergaard approach, by examined six rectangular and six circular models of elevated tanks that suggested by authors through three dimensional finite elements method (FEM), using LUSAS FEA 14.1, based on vibration dynamic analysis to obtain the time of impulsive mass at every case. The results shows a small deviations obtained in both shapes (rectangular and circular) between Westergaard approach and approaches suggested.
