Gross and Net Soil Pressures
In RISAFoundation, the Allowable Soil Bearing value is controlled by the Soil Region. This value is always taken as a Gross allowable soil pressure by default.

Display Enveloped Contour Diagrams for Soil Pressure
RISAFoundation has the ability to display the enveloped contour diagram results for soil pressure. The graphical display of enveloped soil pressures is advantageous because it allows users to quickly identify the degree of influence the loads and slab geometry have on the soil.

Soil Overburden on Mat Slab
RISAFoundation can apply soil overburden to a mat slab to account for the weight of the soil above the foundation. Simply enter a Soil Overburden pressure value for your foundation design in the Slabs spreadsheet. The soil overburden load is utilized to help the mat slab resist overturning during...

Passive Resistance for Mat Slabs
RISAFoundation includes the added ability to enter a passive pressure for slabs. The passive pressure represents soil pressure along the perimeter of the slab and will contribute to the sliding resistance of the slab.
