The "Footing bottom" frame serves to input characteristics of the action of the footing bottom:
- soil from geological profile - the spread footing is founded on the soil assigned from the geological profile specified in the "Profile" frame.
- input parameters of contact base-soil - parameters of the contact between footing bottom and soil are specified. Option "input angle of friction base-soil" requires inputting the friction angle ψ [°] between foundation and soil. Option "input friction coefficient" requires specifying the friction coefficient μ [-]. Both options require inputting the cohesion a [kPa] between foundation (base) and soil.
The input data introduced in this frame influence the spread footing bearing capacity.
