Question:
What do the nine points refer to in the case of any cross-section (Z‑section) in the RF‑/STEEL Warping Torsion?
Answer:
The setting of the load application specified in the Details refers to the principal axes of the respective cross-section. For a Z-section, as an example, a box with nine edge nodes is set around the cross-section. The load application is then always related to the rotated principal axis angle and the corresponding eccentricities.
