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?
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?
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?
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?
When designing seismic equivalent loads with a Response Spectra Analysis (RSA) in RFEM, how can I apply the modal response parameters Ie/R according to Sect. 12.9.1.2 in the ASCE‑7‑16 to my results?
