Low-pressure storage tanks are designed and constructed in accordance with AmericanPetroleum Institute (API) Standard 620 (Ref.1).This standard covers large,field-assembled storage tanks that contain petrole-um gases or vapors as well as other liquid prod-ucts.These large,low-pressure,above-ground tanks are welded from carbon steel.They areImages of Unanchored LIQUID Storage Tanks Transition Secti imagesInfluence of base plate bending stiffness on the seismic Jan 01,2017 unanchored liquid storage tanks transition section plate#0183;M.A.Haroun and H.S.Badawi,Seismic behavior of unanchored ground-based cylindrical tanks,Ninth World Conference on Earthquake Engineering (1988) 643 unanchored liquid storage tanks transition section plate#226;648.
