Extract from AS 4100 (Amdt 1 : 2012)


2.2 STRUCTURAL STEEL

2.2.1 Australian Standards

Except as otherwise permitted in Clause 2.2.3, all structural steel coming within the scope

of this Standard shall, before fabrication, comply with the requirements of the

following Standards, as appropriate:

AS 3597 Structural and pressure vessel steel—Quenched and tempered plate

AS/NZS 1163 Cold-formed structural steel hollow sections

AS/NZS 1594 Hot-rolled steel flat products

AS/NZS 3678 Structural steel—Hot-rolled plates, floorplates and slabs

AS/NZS 3679 Structural steel

AS/NZS 3679.1 Part 1: Hot-rolled bars and sections

AS/NZS 3679.2 Part 2: Welded I Sections

2.2.2 Acceptance of steels

Test reports or test certificates that comply with the minimum requirements of

the appropriate Standard listed in Clause 2.2.1 shall constitute sufficient

evidence of compliance of the steel with the Standards listed in Clause 2.2.1.

Example – Design to DTS Provisions


No test certificate


The fabricator advises

… some of the steel is not 300PLUS, as you specified, and we

don’t have a test certificate for it, BUT we had the steel tested

with the following results for Yield Strength:

320 MPa

310 MPa

315 MPa

Minimum: 310 MPa

Average: 315 MPa

Alternate solution ?

11

If you were the designer would you accept this steel as a design using the alternate solution provisions?

No test certificate


You have these results

320 MPa

310 MPa

315 MPa

If you were the designer would you accept this steel as

a design using the alternate solution provisions?

Minimum: 310 MPa

Average: 315 MPa

Evidence of suitability (BCA A2.2)

Have :

•3 Test results for 1 mechanical property

Don’t have:

•Evidence they were NATA accredited tests (or equivalent)

•Dimensional & mass tolerances

•Cambers or Sweep

•Chemical composition

•Surface defects

Given what you have and don’t have would you accept this steel for an Alternate Solution ?


Evidence of suitability (BCA A2.2)

Assume you now have :

•3 NATA test results for 1 mechanical property

•Dimensional & mass tolerances

•Cambers & Sweep

•Chemical composition

•Surface defects

And all are OK

Who will accept this steel for an Alternate Solution?
