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
- Specifique au projet standard reference

Model Basis
| Theory | Euler-Bernoulli beam theory |
| Main hypothese | Plane sections remain plane |
| Best fit | Slender beams with small deflections |
| Member rigidite | Constant E and I over the span |
| Actuel preset | Simply supported beam with full-span UDL |
| Typical use | Beam checks and teaching examples |
Notes techniques
- Use this page when you want the standard elastic poutre model without project-standard framing around it.
- The model is appropriate pour slender structural members where effort tranchant deformation et large-rotation effects are not governing.
- When continuity, partial fixity, or multiple appuis start to control the response, switch to the advanced poutre pages that use the FEA-based solveur.
