Internal Design Pressure Affecting Overturning Moment
Internal Design Pressure Affecting Overturning Moment
(OP)
Probably a simple one....
As per API 650 why does the internal design pressure of a tank have any bearing on the overturning moment? Why is only the uplift taken into account whereas the pressure would act equally in all directions so the downward pressure would cancel out the uplift.

Sorry please could you explain "because the bottom has no strength in that direction".
If the pressure is acting in all directions it would surely be pushing the bottom plates down just as much as creating uplift on the roof.
