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 3 steel reference

Steel Beam Eurocode 3 Setup
| Material basis | Structural steel with E about 210 GPa |
| Typical beam family | I and H sections in building frames |
| Current preset load case | Mid-span point load on a simple span |
| Typical sequence | Elastic response first, project SLS limit second |
| Useful companion | Eurocode load combinations page |
| Current preset | 6 m steel beam with 18 kN point load |
Engineering Notes
- This page is more steel-specific than the broader Eurocode 3 page and is useful when the user intent already assumes a steel member rather than a generic beam.
- In steel serviceability checks, the modulus is stable and the section stiffness usually drives the outcome, so choosing the right inertia value matters more than choosing between nearby structural grades.
- If the governing action comes from combined dead and live effects, move next into the Eurocode load combination page and bring the resulting line load back into the calculator.
