foundation design with post tensioned suspended floors

[sanji02]

Hi,

from:
Bentley RAM SS, Other Considerations Exporting to RAM SS
"If you are using Ram Foundation to design foundations supporting Concrete Columns, those foundations will not be designed including the Hyperstatic forces from post-tensioned levels above."

I do not understand, but taking a guess:
Is this referring to the compressive forces (resulted from post tension) from levels (I imagine mostly only from the next 1-3 levels above foundation level?) above foundation, and how these horizontal forces will transfer loads (assumed this is not a sway frame bldg) horizontal shear forces through the column and to the foundation?

No this is not the compressive force, it is referring to the secondary effects resulting from the structure continuity.
