Calculation basis
pe = Iw·q·Ce·Ct·Cg·Cp; pi = Iw·q·Ce·Ct·Cg·Cpi; pnet = pe − pi.
Important engineering note: This tool does not determine climatic q values, exposure category, gust factors, pressure zones, dynamic response or cladding/local coefficients. Verify all inputs against NBCC 2025 and the code adopted by the province or territory.

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.
