AS 4100 (2020)

AS 4100 (2020) is the primary standard for structural steel design in Australia. It specifies requirements for the design, fabrication, erection, and modification of steelwork in buildings and structures using limit state methods. The standard covers checks for axial forces, bending, shear, and combined actions.

In SDC Verifier, AS 4100 (2020) is implemented with support for a wide range of symmetrical sections including:

• I-beams (doubly symmetric)
• Channels (singly symmetric)
• Circular and rectangular tubes
• Circular and rectangular bars

The standard includes design parameters such as residual stresses, moment modification factors, lateral restraint conditions, and section constants—all configurable through the interface.
