1893:1984.For seismic design of liquid storage tanks,IS 1893:1984 has very limited provisions.These provisions are only for elevated tanks and ground supported tanks are not considered.Even for elevated tanks,effect of sloshing mode of vibration is not included in IS 1893:1984.Moreover,compared with present international practiceWater Tank Roof Loading - Structural engineering general Feb 24,2005 ground supported liquid storage tanks roof loads#0183;I want to get some second opinons on what would be the acceptable loading for the roof of a water tank.Normally I would think that the Roof Live Loads or Snow Loads as specified in AWWA and ASCE would be used.However I have seen some situations where because the roof is accessible by ladder the ASCE live load for promenades of 60 psf was used.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
