In RISAFoundation v11.0 there are two new tabs in the Safety Factors results spreadsheet that breakdown the slab’s stabilizing and destabilizing forces for each category. The new Overturn/Resist by Category and Sliding/Resist by Category tabs make it easy to understand how the program calculates the safety factor results for a mat slab demand and resisting […]

RISAFoundation v11.0 can now 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 the analysis. The soil […]

RISAFoundation v11.0 now 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. RISAFoundation will multiply the passive pressure by the vertical area along the slab’s perimeter in both the slab’s local […]
