  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. Soil Parameters

    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. Example Model

    Punching Shear Design with Definition of Perimeters

    With RF-PUNCH Pro, the punching shear design can be performed according to 6.4, EN 1992-1-1. In the following example, the design according to DIN EN 1992-1-1 will be presented first with automatic design of the inner and outer perimeters and then on the basis of the inner perimeters defined by the user on a simple example.

  4. 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]).

  5. 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.

  6. Figure 01 - Selecting Method for Determining Load Increasing Factor β

    Determining Load Increasing Factor β with Sector Model

    The RF-PUNCH Pro add-on module allows you to perform punching shear designs according to EN 1992‑1‑1 [1]. In addition to the designs of single columns, it is also possible to analyze wall ends and wall corners in RF‑PUNCH Pro.

    At this point, I would also like to reference a previous article about RF‑PUNCH Pro, which explains how to determine punching load on wall ends and wall corners.

  7. Figure 01 - Data for Determining Allowable Soil Pressure

    Determining Bearing Resistance According to EN 1997-1

    In addition to the reinforced concrete design according to EN 1992‑1‑1, RF‑/FOUNDATION Pro allows you to perform geotechnical designs according to EN 1997‑1.

    In RF‑/FOUNDATION Pro, the design of the allowable soil pressure is performed as a ground failure resistance design. If you select CEN as National Annex, you have two options for defining the ground failure resistance. First, you can directly specify the allowable characteristic value of the soil pressure σRk. Second, there is also the option to analytically determine the bearing capacity according to [1], Annex D.

  8. DXF Export of Results on Surfaces

    DXF Export of Results on Surfaces

    Until the program version of RFEM 5.06.1103, it was only possible to export the results on surfaces in the form of isolines into a DXF file. As of the program version 5.06.3039, it is now also possible to export the results in the Isobands display option.

  9. Generating Help Nodes for Dimension

    Generating Help Nodes for Dimension

    In RFEM and RSTAB, it is possible to add user‑defined dimension lines to a structural model. When creating these dimension lines, click the objects (for example end nodes of a line, members, etc.) which represent the reference points of the dimension. If you want to add a dimension line free from the structure previously defined in the model, you have to create an additional free ‘help node’ which acts as a reference object for the new dimension.
