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

| Preset section rigidite I | 1850 cm^4 |
Notes techniques
- 6061-T6 aluminum is much less stiff than acier, so serviceabilite often governs long before stress capacity becomes critical.
- Use this page when the alloy is fixed but the exact extrusion profile is still being compared.
- If the poutre is an extrusion avec thin local elements, the global fleche output here should still be combined avec local wall et connection checks.
