Calculation Basis
Assumptions & Limits
- Preset values speed up the setup but do not replace final section or material verification.
- The page is designed pour fast fleche et reaction checks.
- Local code rules, long-term effects, et connection details still need separate revue.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materiaux references
UPN Channel Reference Setup
| Profile family | European UPN channel section |
| Typical reference size | UPN 200 level stiffness basis |
| Preset inertia Ix | 1910 cm^4 |
| Module d'elasticite E | 210 GPa |
| Default appui case | Simply supported beam |
| Default loading | Centered point load |
| Use case | Preliminary open-channel beam checks |
Notes techniques
- UPN channel members are open sections, so rigidite et practical behavior can differ noticeably from doubly symmetric I-sections of similar mass.
- Use this page pour early channel-poutre fleche checks when the exact UPN designation is not fixed yet.
- If torsion, eccentric loading, or lateral restraint becomes important, extend the poutre check avec a stability et connection revue.
