Question:
Is it possible to use high-strength reinforcement or high-strength reinforcing steel in the RF‑CONCRETE add-on modules?
Answer:
Yes, it is possible to select high-strength steel SAS 670 for nonlinear design in RF‑CONCRETE Members. This way, you can perform stability analysis for columns, among other things.
The steel can be selected in the Materials section of the add-on module (see Image 01). Since DIN EN 1992‑1‑1 only allows fyk = 500 N/mm² by default, this limit must be adjusted when using SAS 670.
In General Data, you can create a user-defined National Annex where the maximum value of the yield strength is increased to fyk ≥ 670 N/mm² in Point 3.2 (see Image 02).
