  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 - System and Loading

    Nonlinear Analysis in RF-/CONCRETE

    When designing reinforced concrete components according to EN 1992‑1‑1 [1], it is possible to use nonlinear calculation methods to determine internal forces for the ultimate limit state and the serviceability limit state. In this case, the internal forces and deformations are determined with respect to their nonlinear behaviour. The analysis of stresses and strains in cracked state usually provides the deflections, which clearly exceed the linearly determined values.

  3. Figure 01 - Curtailment of Longitudinal Reinforcement from [1]

    Displaying Curtailment of Longitudinal Reinforcement and Reinforcement Covering Line

    In the case of a huge amount of reinforcement, it might be useful to grade the longitudinal reinforcement of a beam. The grading corresponds to the tensile force distribution. Using RF-CONCRETE Members and CONCRETE, you can specify the curtailment of the reinforcement, which is considered in the automatically proposed reinforcement for the longitudinal reinforcement. When determining this reinforcement proposal, it is necessary to ensure that the envelope of the acting tensile force can be absorbed.

  4. Downstand Beams, Ribs, T-Beams: Shear Joints

    In the construction process, it is often necessary to fabricate the concrete elements in sections. A classic example of this production in sections is the use of prefabricated downstand beams, in which the slab is completed in the on‑site concrete construction. By creating a new concrete area, interfaces may arise between the already hardened concrete and the fresh concrete. The transfer of the longitudinal shear forces arising between the partial cross‑sections must be considered in the design.

  5. Improved Result Output for Nonlinear Reinforced Concrete Design

    Improved Result Output for Nonlinear Reinforced Concrete Design

    As of RFEM 5.6.1103 and RSTAB 8.6.1103, there is an improved result output for nonlinear calculation of reinforced concrete design in RF‑CONCRETE Members and CONCRETE. The new result windows include tables with a wide range of loading results, for example governing load with the maximum ratio. In addition, it is now also possible to display the envelope results for the maximum ratio graphically.

  6. Setting Crack Width Analysis in (RF-/)CONCRETE (Members)

    Setting Crack Width Analysis

    As of the program version X.06, you can set in RF‑CONCRETE Members or CONCRETE whether the crack width analysis should be performed in any case or only when exceeding the effective tensile strength of concrete.

  7. Figure 01 - Exporting National Parameters of EN 1992-1-1

    Exporting National Parameters of EN 1992-1-1

    It is possible to export the national parameters of EN 1992‑1‑1 for each country from RF‑/CONCRETE, RF‑/CONCRETE Columns and RF‑/FOUNDATION Pro. For this, there are the interfaces with MS Excel, OpenOffice, and CSV. By exporting the national parameters, you can edit them in MS Excel, for example, and display possible differences between the individual National Annexes in a clear way (see Figure).

  8. Adjusting Result Window 2.2 Required Reinforcement in (RF-)CONCRETE (Members)

    Adjusting Result Window 2.2 Required Reinforcement

    Using the [To Display...] button, it is possible to specify the amount of reinforcement to be displayed in the results of the required reinforcement in Window 2.2 of RF‑CONCRETE and CONCRETE. In addition to the default setting, you can display the resulting reinforcement amount in this way, for example the sum of longitudinal and longitudinal torsion reinforcement or the sum of torsion and shear reinforcement. You can also reduce the number of preset results, of course.

  9. Working in "3D Rendering of Reinforcement" Dialog Box in (RF-)CONCRETE (Members)

    Working in '3D Rendering of Reinforcement' Dialog Box

    In CONCRETE and RF‑CONCRETE Members, you can open a dialog box with a 3D rendering of the existing reinforcement in Window 3.1 or 3.2. Now, it is also possible to display different reinforcement views in several dialog boxes at the same time. The ‘Isometric and 3 Views’ option known from RFEM is available here as well.

  10. User-Defined Factors for Shear Joint Design in RF-/CONCRETE (Members)

    User-Defined Factors for Shear Joint Design

    The shear resistance design value of a joint depends mainly on the formation or the roughness of the connection. When determining the ultimate limit state, this is considered by both factors µ (friction) and c (adhesion percentage of contact area of the composite concrete).
