Calculation basis
A is calculated from idealized geometry. Ix and Iy are centroidal second moments of area; W = I / c and r = √(I/A).
Important engineering note: Use manufacturer or certified section properties for final design of rolled or cold-formed proprietary sections. Transparent preliminary engineering checks with user-visible assumptions and formulas. Final design must be verified to the applicable code, National Annex and project requirements.

Frequently asked questions
Is this a complete code design?
No. It is a transparent preliminary calculation. Code-specific limits, detailing, stability and project conditions must be verified independently.
Can I use the result for construction?
Use the result as a screening or checking aid only. Final design and construction documents should be verified by a qualified professional where required.
Why are some resistance factors entered by the user?
Many design standards contain member-, material-, product- or project-specific values. Metric Republic keeps these visible and user-controlled instead of hiding assumptions.
