What is the purpose of the function "Design of longitudinal reinforcement for percentage of utilization" in the setting for nonlinear calculation in RF‑CONCRETE Members? I have selected this option, but the system is unstable anyway. Why?
I would like to calculate a hall frame with loads from a crane runway. It is not quite clear to me what the various action categories denote. Can you explain it to me?
In the RF‑CONCRETE Surfaces add-on module, I get a design failure for the serviceability limit state (SLS) and no values are displayed for the steel stresses. Also, Message 239) is displayed. Why?
What does the design information mean: Geometry error left side: End plate of the girder: Lambda2 >1.4 Column flange: Lambda2 >1.4 I cannot find an explanation in the manual or online.
How do I specify in FOUNDATION Pro which load is used for the design of the first core width, and which load is used for the design of the second core width?
I designed a wall with RF‑CONCRETE Surfaces. On the outside and inside, the program shows me the same reinforcement amount [cm²/m]. Do I have to enter As,top + As,bottom now? Or only one value (top or bottom)?
After entering the support widths in the RF‑CONCRETE Members add-on module and starting the calculation, the following error message appears: "The support width is too wide!" What should I do?
How can I perform the fatigue design of reinforced concrete and prestressed concrete in RFEM 5? I have found a result combination for fatigue, but cannot find the design in the add-on modules.
Do you have a program for designing columns restrained in concrete? It is not about the design of the bucket, but about the required embedment depth, the provided concrete stress, the check of the shear stress in the column, and so on.
