THEMA:

Looking at this calculation as well as the input data for the software that calculates this, I see that in Steckner's calculation the upper edge of the foundation is always level with the ground level, so that the:
D = height of the foundation = the depth of the foundation.

Does anyone know what to do in case the upper edge of the foundation is above ground level?

Both in the utilization control (nachweis der gebrauchstauglichkeit) and in the stability control (nachweis der standsicherheit) D appears in too many formulas, and the real question is whether in some formulas it should be the height of the foundation, while in some it may only be the depth of the foundation. Or maybe some formulas just need to be different if H (foundation height) is not equal to D (foundation depth)?

Air has no preassure resistance. In this respect, the "stick out" is irrlevant. Just add it to the vertical Loads.

Yes, I know that it affects the results in terms of external forces, but when calculating the stability, the inclination or angle of rotation of the foundation may depend on the true height of the foundation and not only the depth, therefore it may also affect the reactive forces in the ground that depend on the angle of rotation.
