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
C Channel Reference Setup
| Profile family | Cold-formed or hot-rolled C-channel |
| Actuel rigidite basis | Channel reference inertia |
| Default appui case | Simply supported beam |
| Default loading | Full-span uniform load |
| Main ingenierie risk | Open-section sensitivity to torsion and restraint |
| Use case | Preliminary channel member serviceability check |
Notes techniques
- C-channel members are often chosen pour compact framing, edge members, et secondary acier, but their open shape makes them less forgiving than closed or doubly symmetric sections when restraint is weak.
- This page focuses on the global vertical fleche check first, which is usually the fastest first pass before a more detailed channel-specific revue begins.
- When the channel works eccentrically, carries shelf angles, or lacks lateral restraint, pair this page avec stability checks et connection revue.
