Steel design to AS 4100 (Australian).

For projects to Australian standards, Volex Anvil designs steel beams to AS 4100:2020: the section moment capacity φMs, the member moment capacity φMb including lateral buckling, the shear capacity φVv, and the serviceability deflection, each referenced to its AS 4100 clause.

The capacity factors and section properties follow AS 4100:2020, so the φMs and φVv match the OneSteel/ASI design-capacity tables used in Australia.

Frequently asked

Does it include lateral buckling?
Yes — the member capacity φMb applies the slenderness reduction αs and the moment- modification factor αm of AS 4100 §5.6.
Which capacity factor?
The φ factors of AS 4100:2020 are used, matching the ASI design-capacity tables.
Is it validated?
The section moment and shear capacities are checked against AS 4100:2020 — within 0.00%.
Free tier?
Yes — 10 calculations a month free; Pro (£29/month) adds unlimited runs and PDF calc sheets.
