  1. Option "Nonlinear Calculation" in Window "1.1 General Data" in RF-CONCRETE Members

    Exporting Spring Stiffnesses from RF-/FOUNDATION Pro and the Influence on Column Design

    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.

  2. Figure 01 - Hinged Column

    Determination of Bearing Resistance with "Drained" and "Undrained" Soil Conditions

    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.
  3. Figure 01 - Structural System with Loads

    Design of Foundation Rotation

    Using RF-/FOUNDATION Pro, it is possible to perform geotechnical design according to EN 1997‑1 [1] for single foundations. The following article explains the design of highly eccentric loading in the foundation core according to DIN EN 1997‑1, A 6.6.5 (see [3]).

  4. Figure 01 - Activating Ground Water Level for Soil Profile

    Influence of Ground Water Level on Design in RF-/FOUNDATION Pro

    Using RF-/FOUNDATION Pro, it is possible to perform geotechnical design according to EN 1997‑1 [1] for single foundations. Subsequently, the program displays detailed information about the influence of the ground water level on the selected design according to EN 1997‑1.

  5. 1 - Time-Dependent Settlement Components [2]

    Settlement Calculation of Single Foundations According to DIN 4019 in RF-/FOUNDATION Pro

    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. The results of the settlement, foundation tilting, and vertical soil contact stress distribution are displayed graphically and in tables to provide a quick and clear overview of the calculation performed. In addition to the design of the foundation settlement in RF-/FOUNDATION Pro, the structural analysis determines the representative spring constants for the support and can be exported to the structural model of RFEM or RSTAB.

  6. Soil Profile

    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.

  7. Adjusting Secondary Bucket Reinforcement

    In RF-/FOUNDATION Pro, there is the relevant reinforcement concept for each design of bucket reinforcement by default.

  8. Graphical Schema of Required Bending Reinforcement

    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.

  9. Approach 2* According to EN 1997-1

    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.
