Calculation Basis
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
Cold Formed Acier Setup
| Member focus | Light-gauge and cold formed steel beams |
| Typical use | Joists, purlins, and secondary framing |
| Main risk | Deflection can govern before strength in slender members |
| Actuel poutre case | Simple span under UDL |
| Actuel preset | 4.2 m light-gauge beam under 1.8 kN/m |
| Useful companion | Custom wood and standard steel pages |
Notes techniques
- Cold formed acier members can feel serviceabilite-sensitive because rigidite drops quickly as section depth et thickness reduce compared avec hot-rolled poutres.
- This page is most useful during early option comparison, when the user needs to know whether a light-gauge solution remains realistic at the target portee.
- If the section is moving toward heavier hot-rolled acier, compare the resultat avec the Eurocode 3 or British Standard acier pages.
