Question:
Why are there no concrete stresses displayed in the RF‑CONCRETE Surfaces add-on module?
Answer:
If you want to display the concrete stress or the corresponding design, select the corresponding point in "Settings for Analytical Method of Serviceability Limit State Design" (see Figure 01).
If the concrete stress is calculated, another point called "Concrete Stress" appears in the Results navigator. In the intermediate results of the concrete stress, you can display the stresses in both State I and State II (see Image 02).
