Software Etank2000 or Coade Tank 3.5

Dear duazo2009,

E-tank and Tank can do what API 650 considers as formulas.
API 650 does not introduce formulas for roof calculation, except self-sustained roofs. Or, better said, there are in API 650 few formulas referring to plates thickness but not for beams which sustain the plates.
E-tank additionally introduced column sustained roof formulas from books- so using them it would be the question of validation of such approach. I mean that calculation is OK but it isn't really an API calculation.
No chance to calculate by such software a more complicated roof structure, let's say a dome structure.

What about floating roof? It is capable?
