anchored liquid storage tanks Allowable design stresses for bolts

tank roof uplift - API (American Petroleum Institute) Code

May 11,2006 anchored liquid storage tanks Allowable design stresses for bolts#0183;Stresses from the uplift are contained within the dome roof and not transmitted to the tank other than vertical uplift.The uplift of the dome would tend to offload the tank structure,making it a non-critical load case and is safely ignored for the tank design. The tanks are anchored for overturning with bolt chairs,so if the tank moves design problems of anchoring of aboveground steel tanks The current research of the tanks in which anchor bolts,respectively chairs (Fig.2),must bear tension and shearing forces,has the following purpose - to check how the stress-strain state changes in the shell in the zones of anchors chairs; - to check whether the anchor bolts are bended when the tank is being filled and consecutive shell design problems of anchoring of aboveground steel tanks The current research of the tanks in which anchor bolts,respectively chairs (Fig.2),must bear tension and shearing forces,has the following purpose - to check how the stress-strain state changes in the shell in the zones of anchors chairs; - to check whether the anchor bolts are bended when the tank is being filled and consecutive shell
