Question:
How can I design any SHAPE‑THIN cross-section in detail in RFEM or RSTAB?
Answer:
Any SHAPE‑THIN cross-section can be designed as follows:
Stability and stress analysis with the RF‑/STEEL EC3 add-on module and the RF‑/STEEL Warping Torsion module extension; see Image 01
Generating surfaces from the cross-section (possible in RFEM only; see Image 02), and a new definition of support and stress analysis of the newly created surfaces with RF‑STEEL Surfaces, if necessary (see Image 03); under certain circumstances, a stability analysis with RF‑STABILITY for the surface model is reasonable (see Image 04).
