Calculation Basis
Assumptions & Limits
- Preset values speed up the setup but do not replace final section or material verification.
- The page is designed for fast deflection and reaction checks.
- Local code rules, long-term effects, and connection details still need separate review.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materials references
LVL Material Reference
| Material family | Laminated veneer lumber (LVL) |
| Preset product basis | Kerto-S style LVL beam |
| Mean elastic modulus | 13.8 GPa |
| Example member | 63 x 300 mm section |
| Example area A | 189 cm^2 |
| Example inertia I | 14175 cm^4 |
| Preset loading | Full-span uniform load |
Engineering Notes
- LVL often sits between conventional sawn timber and heavier steel solutions, especially where long spans and low dead load are both important.
- This page uses a Kerto-style modulus preset, but the real LVL grade and manufacturer table should still be confirmed before design decisions are locked in.
- Many LVL checks begin with the product family first, so the stiffness input should be updated to match the exact manufacturer data in use.
