Question:
Window "1.2 Geometry", the "Supports" tab, provides the selection between none, rigid, or non-rigid stiffener. How does this affect the calculation?

Answer:
The stiffener type selected in the "Supports" tab of Window "1.2 Geometry" (Image 01) has an effect on the buckling analysis of the beam, as this affects the contribution of the web χ-W to the shear resistance according to EN 1993‑1‑5 [1], 5.3.

The factor χ-W for the web contribution to the shear resistance is displayed in the result table for the buckling analysis (Image 02).
