Calculation Basis
Assumptions & Limits
- The page supports preliminary checks but does not replace full code compliance review.
- Allowable limits remain project-specific and must be checked separately.
- Elastic modulus, inertia, and loading inputs must match the real member.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materials references
- Eurocode 5 timber reference
Custom Wood Beam Setup
| Material focus | Custom sawn timber or engineered wood |
| Main task | Compare candidate wood beam sizes against deflection |
| Current sample member | 75 x 210 mm style beam stiffness |
| Current beam case | Simple span under UDL |
| Current preset | 4.5 m wood beam under 2.2 kN/m |
| Useful companion | Eurocode 5 timber and timber span pages |
Engineering Notes
- This page is intended for users who begin with a rough timber size and want a fast answer on whether that section is still in range for serviceability.
- It works well as a sizing bridge between generic timber rules of thumb and more specific timber pages tied to Eurocode 5 style checks.
- Because timber stiffness varies by product and grade, the elastic modulus should be updated to the real material before the result is used beyond preliminary sizing.
