These are a few a know (the most conservative first
API uses B=0,37R. But this is not realistic.
There is also a method used by AEC B=0.41R^2
EEMUA uses B=2R.
Table B10 and B11 is only used for lapwelded plates. So this isnot used for tanks with a annular ring. Is this correct?
And what does ASME say about settlement? I have not found anything about.
