Tank Settlement Vs. SBC from Shear
Tank Settlement Vs. SBC from Shear
(OP)
Hello!!
I would just like to ask..
is it ok if Tank Load is greater than allowable soil bearing capacity (ex. Tank Load = 18ton/sq.m, SBC = 14 ton/sq.m) as long as it passes allowable settlement criteria?
Thanks in advance!!

It is my view that
1. Any time you use the word "capacity" you are basing your premise on shear strength. Ultimate bearing capacity is as the formulas (whichever one you use) give you - the allowable bearing capacity is the ultimate divided by a factor of safety (usually 3).
2. When one uses, as a premise, settlement or distortion, it should be referred to as "allowable bearing pressure" - usually "net". This clearly defines that the given or quoted value is settlement or distortion driven.
I don't use the term SBC (Safe bearing capacity) - mainly because of the two points above. In most soils, it is the settlement and/or distortion criteria that govern the applied loads.
