You can identify the cross-sections suitable for the design by moving the cursor over the individual "Parametric - Massive" cross-sections. A window appears with information about where the respective cross-section can be designed (see the image).
Cross-Sections Suitable for RF-CONCRETE Design
Which cross-sections can I design in RFEM 5 with RF‑CONCRETE Columns and in RF‑CONCRETE Members?

The aim of this technical article is to perform a design according to the general design method of Eurocode 2, using the example of a slender reinforced concrete column.



The "Nonlinear Material Behavior" add-on includes the Anistropic | Damage material model for concrete structural components. This material model allows you to consider concrete damage for members, surfaces, and solids.
You can define an individual stress-strain diagram via a table, use the parametric input to generate the stress-strain diagram, or use the predefined parameters from the standards. Furthermore, it is possible to consider the tension stiffening effect.
For the reinforcement, both nonlinear material models "Isotropic | Plastic (Members)" and "Isotropic | Nonlinear Elastic (Members)" are available.
It is possible to consider the long-term effects due to creep and shrinkage using the "Static Analysis | Creep & Shrinkage (Linear)" analysis type that has been recently released. Creep is taken into account by stretching the stress-strain diagram of the concrete using the factor (1+phi), and shrinkage is taken into account as the pre-strain of the concrete. More detailed time step analyses are possible using the "Time-Dependent Analysis (TDA)" add-on.

In the Concrete Design add-on, you can determine the required longitudinal reinforcement for the direct crack width analysis (wk).

For the design of reinforced concrete members, there is the option to automatically determine the number or diameter of rebars.

For concrete design, you can display the reinforcement results in tables separately by design situation.
How can I understand the calculation of the required reinforcement?
