PORJECT:- ARZOO
Rough design of tank ring foundation
Dia of tank 19.5 m
Height of tank 22 m
Base area of tank = x R2
298.6 m2
Volume of tank = x R2
XH 6570.25 m3
Consdier full of water ( test condition)Unit weigt of water = 10
Kn/m3
Total weight of tank content = 65702.48 Kn
Hight of soil soil below tank (H1+H2)= 1.5 m
Weight of soil soil below tank = 8063.5 Kn
Weight of content + soil below (W1) = 73766.0 Kn
Add 10% of "W1" for self weight = 7376.6 Kn
Total Load = 81142.6 Kn
Pressure Below the tank = 271.7 Kn/m2
So required SBC at 1 m depth = 210 O.K
We can increase 20% of SBC for test load 252 Kn/m2
Over burden height = 1.5 m
Over burden pressure = 27 Kn/m2
Increased SBC = 279 Kn/m2
For seismic and wind forces the "Sbc" may change
