Calculation basis
qd = γG·gk + γQ·qk; MEd = qd·L²/8; VEd = qd·L/2; MRd = Wy·fy/γM; VRd = Av·fy/(√3·γM); winst = 5·qser·L⁴/(384·E·I).
Important engineering note: This is not a complete EC3/AISC/CSA/GB member design. It does not check lateral-torsional buckling, local/classification effects, concentrated loads, web buckling, stability, fatigue, fire or connections. 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.
