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?
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.
Is it possible in RF‑CONCRETE Surfaces to model a prefabricated slab or an element slab with different reinforcement layouts; for example, a reinforcement layer in a precast element and another reinforcement layer in the cast-in-place concrete extension?
When selecting the nonlinear method of check in the serviceability limit state design, there is the option to export the stiffness of the already cracked structure. Is it possible to recalculate the internal forces with these stiffnesses?
In connection with the nonlinear calculation for the serviceability limit state design checks, I obtain implausibly large values for crack width and deformation in the RF‑CONCRETE modules (see Image 01). What is the cause, and how can I fix the problem?
I have designed several reinforced concrete surfaces of my model using the RF‑CONCRETE Surfaces add‑on module, and now I get no results in the display of the required shear reinforcement a-sw in sub‑surfaces. What can be the reason?
After dividing a column with intermediate nodes, the results in the RF‑/CONCRETE Columns add-on module are different from those before the division. What can be the reason?
Why do I get message 28) in RF‑CONCRETE Members saying that I have to make a "calculation without second order effect" with the internal forces according to the geometrically linear analysis?
Is it possible to adjust the initial values of the temperature courses entered for the fire resistance design? For example, I would like to adjust the initial value of the moisture content.
In connection with the analytical SLS calculation, I get implausibly large values for the crack width and deformation in the RF‑CONCRETE add-on modules. What is the cause, and how can I fix the problem?
