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
Long-Term RC Reference Setup
| System type | Reinforced concrete beam |
| Model basis | Reduced effective stiffness estimate |
| Preset effective modulus | 12 GPa |
| Preset effective inertia | 25000 cm^4 |
| Preset appui case | Simply supported beam |
| Preset loading | Uniform sustained load |
| Use case | Preliminary long-term serviceability check |
Notes techniques
- This page is not a full long-term reinforced concrete fleche model avec cracking evolution, creep coefficients, shrinkage, tension stiffening, et staged loading.
- It is a simplified reduced-rigidite check pour testing whether a long-term serviceabilite issue is plausible.
- Pour real design, the effective rigidite et long-term multipliers must be taken from the chosen code method et actual reinforcement/layout hypotheses.
