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.
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?
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?
When determining the effective cross-section properties according to EN 1993‑1‑1, EN 1993‑1‑5, or EN 1999̩1‑1, SHAPE‑THIN displays a warning message saying that the effective widths are only determined for straight elements. What does this mean?
What are the options in RFEM 5 or RSTAB 8 for determining the ideal elastic critical moment for lateral-torsional buckling for any cross-sections and systems/loads? Is it also possible to design flat steel (brackets, flat steel stringers of staircases)?
When designing a beam, I would like to neglect the torsion included in the stability analyses using the filters described in Knowledge Base article #001498.
I define the filter, but the torsion warning appears at the same x‑location again. Do the design internal forces change, or why is that?
