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
Composite Reference Setup
| System type | Composite steel-concrete beam |
| Model basis | Equivalent elastic stiffness estimate |
| Acier modulus E | 210 GPa reference |
| Preset equivalent inertia | 18000 cm^4 |
| Preset appui case | Simply supported beam |
| Preset loading | Uniform load |
| Use case | Preliminary serviceability estimate |
Notes techniques
- This page uses a simplified equivalent-rigidite approach, not a full composite poutre design model avec staged construction, creep, cracking, or connector-slip modeling.
- The preset works as a fast equivalent-EI estimate pour an early serviceabilite check before detailed composite design.
- Pour final design, the effective rigidite should come from the actual composite section, effort tranchant connection level, et design standard rather than from a generic preset.
