Abstract

The aim of this article is determination of seismic response of cylindrical steel tank situated at Al Hoceïma city in Morocco. When a storage facility containing liquid starts moving due to earthquake loading, the fluid filling exerts additional hydrodynamic pressure on storage facility solid domain. The seismic effect of a liquid–filled storage facility converts the contained liquid into and equivalent spring-mass system representing impulsive mode together with convective mode of vibration of the storage facility - liquid system. The seismic response of cylindrical steel tank subjected to seismic loading was calculated by using the elastic response spectrum for locality Al Hoceïma city in Morocco. The rules of Eurocode 8-4 were respected for documented seismic analysis of storage facility containing liquid.
