Scope & assumptions

GB 50017-2017 steel-beam screening with user-entered design strengths and beam stability coefficient φb.

Calculation basis

M = qd·L²/8; V = qd·L/2; MR,screen = φb·f·W; VR,screen = fv·Aw; w = 5·qser·L⁴/(384·E·I).
Important engineering note: Determine φb, section classification/effective properties, local buckling, lateral stability, web buckling and all GB 50017-2017 applicability limits from the standard and current mandatory general codes.

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.
