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?
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?
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.
In FOUNDATION Pro, I get extremely large foundations for my structure or I have to enter a very high loading in order to fulfill the design of the foundation torsion. What can be the reason?
I would like to save foundations with certain dimensions as a template in the database. Is this possible? The button for this is disabled in Window "1.2 Geometry".
Why is the "By taking into account the deformation ratio of the longitudinal reinforcement" method inactive in the detail settings for the SLS design in RF‑CONCRETE Surfaces?
How can I retrace the detailed results or the intermediate results of the serviceability limit state design checks in RF‑CONCRETE Surfaces? For the required reinforcement, the SLS info button is inactive.
Is the RF‑CONCRETE Surfaces add-on module able to determine and calculate a required reinforcement with the corresponding diameter for the design without the direct crack width analysis according to EN 1992‑1‑1, 7.3.3?
Why is it possible to switch off the individual design checks in RF‑/FOUNDATION Pro? After all, this poses a risk for the user to "accidentally" disable certain design checks and possibly design a foundation that is undersized?
I have a foundation that is supported by adjoining frost aprons (distorting beam) in one direction (X- or Y-direction). From the determination of internal forces in RFEM, I get the horizontal support forces in the X- and Y-directions. This is correct. However, the foundations in the X-direction are supported due to the ice wall. Is it possible to "switch off" or neglect the support reaction from RFEM for the foundation design in RF‑/FOUNDATION Pro?
In RF‑PUNCH Pro, Window "1.4 Longitudinal Reinforcement" shows all surfaces connected to the nodes selected for design. For example, in a punching shear design on a wall corner, the surfaces that actually represent the walls are also defined. I can also define a longitudinal reinforcement for these surfaces. Is this reinforcement applied somehow? Why do I see these surfaces in Window 1.4?
