Seismic response of waste storage tanks

Abstract

Ground-supported cylindrical tanks are used to store a variety of liquids. This paper provides the theoretical background for takes into account impulsive and convective (sloshing) actions of the fluid in concrete containers fixed to rigid foundations; it has been adopted in Eurocode 8. Seismic responses-base shears, the bending and overturning moments-are calculated by using the response spectra of the earthquake in Loma Prieta, California. As the examples is analyzed the ground supported cylindrical concrete tanks, where for constant fluid filling H, R are depended from parameters tank slenderness ratio γ = H/R.
