Question

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

Answer:
The stress calculations are performed on the stress points of a cross-section.
Cross-sections of the cross-section types
  • Flat bar
  • 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 shear force or torsion, it is necessary to select solid cross-sections.
