Can I also use the horizontal part of a stress-strain curve for the cross-section design in RF‑CONCRETE Members?


In the case of cross-section design, RF‑CONCRETE Members or CONCRETE uses in the calculation the stress-strain diagram for reinforcing steel according to DIN EN 1992‑1‑1, 3.2.7(2)a, that is, the increasing upper part up to ftk and the strain limitation of εud = 0.025.

In RF‑CONCRETE Members or CONCRETE, there is no option to switch to the design with the horizontal part according to 3.2.7(2)b.

However, you can possibly use a user-defined material with ftk = fyk.
