If Eurocode standard is chosen then the required Design Approach according to [1] 2.4.7.3.4 is to be defined. If a country annex is chosen then the design approach is predefined according to this annex and the partial factors with regard to ground pressure and sliding are set according to this approach.

The user defines foundation depth, the distance from lower edge of slab to ground water level, if slanted neighboring ground surface is present (only  Swedish annex) and the soil weight density above and beneath ground water level. The ground water level can also be situated above the lower edge of slab. The distance is then defined with a negative value. Here is also the soil type defined.

Cohesionless soil

By clicking the button More the following can be defined:

For the case cohesionless soil the characteristic friction slope φ_k and belonging security factor γ_m are defined. For the  Swedish annex a number of suggestions for different soil types can be achieved according to [5] 1.42.

Cohesive soil

By clicking the button More the following can be defined:

Normally consolidated clay

For the case normally consolidated clay the characteristic undrained shear capacity C_uk and belonging security factor γ_m are defined.

Over-consolidated clay

For the case over-consolidated clay an analysis with regard to both undrained and drained conditions is performed. The user defines characteristic values for undrained shear capacity C_uk, for drained shear capacity C_k’, characteristic friction slope φ_k and belonging security factors γ_m.

Medium soil

By clicking the button More the following can be defined:For medium soil an analysis with regard to both un-drained and drained conditions is performed and the most dangerous case will be decisive. The user defines characteristic values for undrained shear capacity C_uk, for drained shear capacity C_k’, characteristic friction slope φ_k and belonging security factors γ_m.

Rock

By clicking the button More the following can be defined:

For the case rock the user defines allowed ground pressure.
