However,in order to achieve this,it is necessary to limit the roof-to-shell strength.So,item 5 was added to accomplish this.You are correct that these items are based on an self anchored tank.However,the addition of anchorage does not significantly affect the shell-to-bottom joint strength with regards to rupture of the corner weld.Venting Aboveground Tanks Part 1 - Tank Types and theMay 01,2000 self anchored storage tanks shell support#0183;Venting of aboveground storage tanks is one of the most difficult aspects of tank engineering to understand. When the design pressure is high enough to require the tank to be anchored,it also tends to require a steeper pitch to the cone roof. supported only at its periphery),the roof-to-shell attachment must be adequate to support 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 Data
