主 题：Floating roof tanks seal master sloshing vertical cylindrical tanks sloshing period damping
摘 要：Liquid storage,particularly oil and petrochemical products which are considered hazardous liquid,are an important part of the oil ***-walled vertical cylindrical steel storage tanks are widely used in recent *** to high sensitivity of these structures in an earthquake and other external excitations may lead to catastrophic *** instance,huge economic losses,environmental damages,and casualities,many studies have been done about these *** studies showed that liquid storage tanks,equipped with a floating roof,are potentially vulnerable while subjected to seismic loads and earthquake has been considered as one of the most destructive natural *** reason is that such tanks are made of two separated parts(shell and roof)which each may have its own responses;sometimes causing resonance phenomenon and so that,roof movements,rooffluid interaction,roof-shell interaction,and also the way they are attached should still be *** tests of floating roof’s vertical fluctuation was performed in a full-scale reservoir tank and assessing of the results demonstrated that presence of a seal between floating roof and shell plate can significantly increase damping ratio in liquid sloshing and also suppress the roof`s vertical *** other words,seal can control a floating roof and make it stop moving vertically over few cycles.
