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
Prestressed Concrete Reference Setup
| System type | Prestressed concrete beam |
| Model basis | Equivalent elastic stiffness estimate |
| Preset effective modulus | 34 GPa |
| Preset effective inertia | 95000 cm^4 |
| Preset appui case | Simply supported beam |
| Preset loading | Uniform service load |
| Use case | Preliminary serviceability estimate |
Notes techniques
- This page is not a full prestress-loss, tendon-profile, cracking, creep, et staged-construction design model.
- The default values help estimate whether poutre flexibility is likely to be a serviceabilite concern.
- Pour real design, effective rigidite et fleche behavior must be tied to the actual tendon geometry, prestress force, losses, construction stage, et code method.
