Walter Fröhlich Results STEEL RF-STEEL

Why do I get different results when calculating the stresses of a flat steel, square or octagonal steel compared to the manual calculation?
Particularly in the case of shear stresses due to shear force and torsion, they deviate considerably.


The stress calculations are performed on the stress points of the cross-section.
Cross-sections of cross-section types

  • Flat steel
  • Square steel
  • Hexagonal steel
  • Octagonal steel
  • Wide flats
receive only circumferential stress points at the corner points.
If a member with one of these cross-sections is subjected to the design by shear force or torsion, the solid cross-sections should be selected.
