  1. Biaxial Load Eccentricities in Cross-Section

    Designing Reinforced Concrete Compression Elements Subjected to Biaxial Bending with the Nominal Curvature Method

    Daily tasks in reinforced concrete design also include designing compression elements subjected to biaxial bending. The following article describes the different methods according to Chapter 5.8.9, EN 1992-1-1, which can be used to design compression elements with biaxial load eccentricities by means of the nominal curvature method according to 5.8.8.

  2. 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.

  3. 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 behavior. The analysis of stresses and strains in cracked state usually provides the deflections, which clearly exceed the linearly determined values.

  4. DXF Exporting Results from RF-CONCRETE Surfaces

    DXF Exporting Results

    RF‑CONCRETE Surfaces performs the ultimate and the serviceability limit state design of slabs, plates, folded plates and shells. In RFEM, the reinforcement resulting from this design can be displayed graphically on the surfaces of the structure using isolines. For the reinforcement design, it may be useful to export the results as isoline distribution in a DXF file in order to open them in a CAD application as background layers.
