How can I design any SHAPE‑THIN cross-section in detail in RFEM or RSTAB?


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 Figure 01

  • Generating surfaces from the cross-section (possible in RFEM only, see Figure 02), and a new definition of support and stress analysis of the newly created surfaces with RF‑STEEL Surfaces, if necessary, see Figure 03; under certain circumstances, a stability analysis with RF‑STABILITY for the surface model is reasonable, see Figure 04.
