Why Dlubal Software?
With RF-FOUNDATION Pro, it is possible to determine settlements of single foundations and resulting spring stiffnesses of the nodal supports. These spring stiffnesses can be exported into the RFEM model and used for further analyses.
The RF-/FOUNDATION Pro add‑on module designs single foundations (foundation plates, bucket and block foundations) for all support forces arising in the RFEM/RSTAB model. The geotechnical designs are performed according to EN 1997-1.
For the serviceability limit state design according to Section 6.6 of Eurocode EN 1997‑1, settlement has to be calculated for spread foundations. RF‑/FOUNDATION Pro allows you to perform the settlement calculation for a single foundation. For this, you can select between elastic or solid foundation. By defining a soil profile, it is possible to consider several soil layers under the foundation base.
As of the program version x.06.1103, it is possible to enter a soil profile in RF‑/FOUNDATION Pro. This provides you the advantage to set several soil layers with different soil parameters above and under the foundation base. For entering the soil layers, there is a library with various soils that can also be extended with user‑defined soils. The user-defined soil profile is shown in an interactive information graphic. Any change, for example a soil thickness modification, is reflected in the graphic immediately.
As of the program version x.06.1103, various optimizations are available. The RF‑/FOUNDATION Pro add‑on module has also been subjected to further development.
Due to RF‑/FOUNDATION Pro, it is possible to perform the geotechnical design of single foundation according to EN 1997‑1 in RFEM 5 or RSTAB 8. Depending on the National Annex preset in the add‑on module, you can determine bearing resistance using Approach 2 or 3 in compliance with EN 1997‑1 up to the Version x.04.0108.
