In the case of open cross -sections, the torsional load is removed mainly via secondary torsion, since the St. Venant torsional stiffness is low compared to the warping stiffness.
- I have performed a buckling analysis in RF-ALUMINUM. Where can I find the parameters that the module uses for the design?
- It is not possible to design a SHAPE‑THIN cross-section due to invalid symmetry. What is the cause and how can I fix it?
- I need to define different types of lateral intermediate restrains for a single element in RF-/STEEL EC3. Is this possible?
I get an implausible result with the expression "1.#J" in the RF‑/ALUMINUM add-on module.
How can I fix it?
- SHAPE‑THIN calculates a very small shear area. Why?
My member is oriented at the inclination of principal axis when I import from SHAPE-THIN to a 2D RFEM model. How do I fix this?
- How can I get the member end forces to design the connections?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- Which Dlubal Software programs are required to calculate membrane and tensile structures?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
