Is is correct that the allowable soil pressure has to be entered as the characteristic value in Window 1.1 General Data of FOUNDATION Pro? Will be the design value determined automatically?

Answer

Yes, this is correct.

The characteristic value of soil pressure is entered in the input window 1.1 General Data. See Figure 01.

The design value is:
${\mathrm\sigma}_\mathrm{Rd}\;=\;{\mathrm\sigma}_\mathrm{Rk}\;/\;\;{\mathrm\gamma}_{\mathrm R;\mathrm v}$

The estimated partial factor for spread foundations can be found in the parameters of the National Annex you have selected for the design. See Figure 02.
