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?
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 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.
I would like to perform the fire resistance design using the EC3 add-on module. Is it possible to intervene in the program in such a way that I can use my own temperature curve instead of the standard one?
For a calculation, I activated the "Detailed Calculation" option. Have the support loads already been specified with the reduced dynamic coefficient for the design of the substructure?
I used double members for the member input. Do I have to consider anything else, or is it better to enter a member with double cross-section properties?
For the fire resistance design, the modulus of elasticity is reduced. I assume that this applies to the design first. However, to what extent is a stiffness change in the structural system and thus a load redistribution considered?
I have to dimension a wall bracket as a steel brackets that I have modeled as surface components in RFEM 5. Which add-on module can I use to design it?
I would like to design banisters, so I have created a set of members for this. The cross-section is a hollow section. Can the stability analysis be carried out on the entire structure, or do I have to convert it into an equivalent member design with the specification of all supports in STEEL EC3?
I have created a 2D frame and would like to assign a lateral and torsional restraint to the ridge. Do I have to enter an intermediate lateral restraint or a nodal support in RF‑/STEEL EC3?
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?
During the calculation, I get a warning that some elements are connected to the buckling panel, but are not defined like stiffeners (see Image 01). What should I do?
When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 160, minimum value 200). What does this message mean?
