Wind loads on fixed-roof cylindrical tanks with very low

Wind tunnel tests are conducted to investigate the wind loads on vertical fixed-roof cylindrical tanks with a very low aspect ratio of 0.275,which is a typical ratio for practical tanks with a volume of 100,000 m3.Both the flat-roof tank and the dome-roof tank are investigated in present study.The first four moments of the measured wind pressure,including the mean and normalized deviation Wind loads on fixed-roof cylindrical tanks with very low Wind tunnel tests are conducted to investigate the wind loads on vertical fixed-roof cylindrical tanks with a very low aspect ratio of 0.275,which is a typical ratio for practical tanks with a Venting Aboveground Tanks Part 1 - Tank Types and theMay 01,2000 fixed roof tanks anchorage ratio#0183;For a tank with a fixed roof and internal floating roof,but without a gas blanket For normal venting,API 650 (G.8.3 and H.6.2) specifies vents in the fixed roof,tank shell and internal floating roof.The vents in the floating roof protect the roof and rim seal and accommodate liquid movement and thermal breathing.
