Calculation Basis
Assumptions & Limits
- The page appuis preliminaire checks but does not replace full code compliance revue.
- Allowable limits remain project-specific et must be checked separately.
- Module d'elasticite, inertia, et loading entrees must match the real member.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materiaux references
- Eurocode 3 steel reference

Eurocode-Oriented Setup
| Material focus | Steel beams with E about 210 GPa |
| Typical check type | Serviceability deflection review |
| Courant poutre case | Simply supported beam under UDL |
| Typical follow-up | Compare output with project-specific SLS limit |
| Useful companion page | L/360 deflection limit calculator |
| Actuel preset | 7 m steel beam under 6.5 kN/m |
Notes techniques
- This page is framed around Eurocode-style acier poutre serviceabilite checks, but it intentionally keeps the calculatrice itself transparent et formule-based rather than pretending to replace clause-level project checking.
- Pour most acier poutres the rigidite driver is section geometry, because the elastic modulus stays near 210 GPa across the courant structural acier grades used in Eurocode practice.
- The correct allowable fleche still depends on the project brief, finishes, occupancy, vibration sensitivity, et national annex expectations, so use the output as a calculation engine et compare it against the governing SLS rule.
