AS 4100

The Australian Standard for steel structure design (Standards Australia).

What it is

AS 4100, “Steel Structures”, is the primary standard for steel design in Australia, used with the AS/NZS 1170 loading suite.

Design method

Limit-state design with a capacity factor φ (typically 0.9): design capacity φRu must be no less than the design action effect from factored loads.

Key checks

• Section and member moment capacity (including lateral buckling)
• Compression capacity — using the form factor kf for slender sections
• Shear and combined actions (axial + bending)
