Notice – Proposed new fatigue design provisions for the forthcoming AS/NZS 5100.6

A regular enquiry received by HERA has been the application of fatigue design in steel bridges. On one hand, some designers have had trouble interpreting the current design rules; whilst on the other, many fabricators have expressed concerns on more expensive butt welds being specified for fatigue details where this might not be entirely necessary.…

Preparing our industry for disruption

We work in an industry based on well-established and traditional materials. Metals have been fabricated for millennia. Applications have historically ranged from warfare, tooling, building and construction and are now evolving into emerging applications such as geothermal energy extraction and biomedical technologies. Metals, such as steel, are known for their high strength, ductility, and formability.…

Resource – SCI publication of free online software for floor vibration

SCI has recently released an online based calculator for floor dynamic response prediction. Compared with the manual method proposed in SCI P354, the calculator investigates the floor vibration using finite element analysis of regular grids. For irregular floor grids, existing tools such as the Oasys design software should still be used. The online tool covers…

Update – ACRS new developments for certificates of compliance

The Australasian Certification Authority for Reinforcing and Structural Steels was founded as a not-for-profit, voluntary, third party product certification scheme in 2000 and issued its first certificates of compliance in 2003 to AS/NZS 4671 for steel reinforcing materials. ACRS now provides additionally certificates of compliance to prestressing steels and structural steels to AS/NZS Standards 4672,…

Update – The role of the Welding Supervisor in quality management schemes

A SFC fabricator has demonstrated that all their welding and related activities are managed under a quality management system that fully complies with the requirements of AS/NZS ISO 3834; specifically for NZS 3404.1 Steel Structures Standard, and AS/NZS 1554 Structural Steel Welding. A quality management system relies on competent people: the fabricators welding co-ordination team. A key…

Notice – Design of composite beams with composite slabs using profiled steel decking

Rules for evaluating the design resistance of headed stud connectors through-deck welded within steel decking are provided in NZS 3404.1, 13.3.2.2. Due to the pitch of the ribs in the deck, it is normally not possible to provide enough shear connectors to provide a resistance equivalent to the lesser of: the tensile resistance of the…

Update – Fabsec F-Beam software remains free to NZ users

No doubt many HERA News readers are aware that New Zealand structural steel designers have had access to the free Fabsec FBEAM® design software. With a total of 159 individual licenses issued in New Zealand, this is a widely-used software package that produces efficient steel designs. Last year, at least 6,000 tonnes of welded beams…
