May 01,2000 API 620 tanks Roof Loads#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.Useful Calculation sheets (excel and mathcad files) for DESIGN OF STEEL STORAGE TANKS AS PER API-650 SELF-SUPPORTED CONE ROOF DESIGN DATA Service HSD SERVICE Allowable Design St Capacity 21 KL Allowable Test Stre Type of tank Self Supported Cone Roof Specific Gravity of L Dia of tank (feet) 10.004 Corrosion Allowance Height of tank (feet) 9.512 Slope of roof 1 5 Slope of bottom Flat Bottom Plate DataThe Code states shall not be less.The important word there is shall. No,because the tank would not meet the minimum requirements.bimr is correct but why would you want to reduce the live load to zero?Ditto to the Why? comment.Note that you can build an open top tank if desired.Once you have enough structure to support the weight of the rAgree with BIMR. Like IFRS and JStephen said there must be a reason why the client request to reduce to 0 In this case open top tank is theThanks for the comments. The only reason for the eliminating the live load was to reduce cost. But I don't believe that cost should be used to ..There are minimum loads for a reason,not the least of which is to have a structure you can walk on if needed. Also,if emissions are a concern,tIFRs you are correct it will be designed with an IFR but it is going to be steel and not aluminum. Again thanks for all the reply's.How do you weld the top side of the roof plates if the roof is not designed to support a live load?fegenbush,sorry for the delay in answering this,but this was also one of my concerns.
