Question:
Can I define a beam with a specific reinforcement in RFEM and then obtain a design of that reinforcement including the design ratio?
Answer:
Yes, this is possible using RFEM and the add-on modules RF‑CONCRETE Members and RF‑CONCRETE NL. For RSTAB, the CONCRETE add-on module is required.
In the design modules of RFEM or RSTAB, you can define "Provided Basic Reinforcement" and perform a nonlinear calculation in the ultimate limit state for this reinforcement.
As a result, you obtain the utilization ratio from the nonlinear calculation assuming the provided longitudinal reinforcement.
Note:
The nonlinear calculation is already included in the CONCRETE add-on module for RSTAB. In RFEM, the RF‑CONCRETE NL add-on module is required.
