Notice – Temperature distribution in typical composite slabs under standard temperature-time fire condition

Temperature-time (T-t) curves and temperature contour plots due to the ISO 834 standard fire loading curve for typical New Zealand composite floors have been calculated and presented in tabulated format. The temperatures in 10 minute intervals up to the requested fire resistance rating have been reported for the slab top face and along the thinnest…

Call for comment – Design software for composite design standard AS/NZS 2327

As the new design standard for composite construction AS/NZS 2327 nears completion, consideration is being paid to what software tools will be needed by designers. Our General Manager Structural Systems Dr Stephen Hicks has encouraged Arup’s software house Oasys to implement the new AS/NZS 2327 within their Compos programme, which enables users to design composite beams…

The evolution of the NZ steel industry – innovation dinosaur or drosophila?

We have an image problem. In experimental evolution, Drosophila (the humble fruit fly) is often used to demonstrate evolutionary processes. It is used because genetic changes for the fruit fly can be observed very quickly in response to natural selection. In business, the equivalent of the fruit fly is the IT or information technology company,…

Notice – Quality requirements for thermal cutting

Flame, plasma and laser cutting are widely used in industry. The selection of the cutting process is based on the type of material, economic considerations and quality requirements. Despite some specifics, high quality results are obtainable using all of the cutting processes. The level of quality required for cut surface is determined by the application…

AGGAT progress update for June

Above Ground Geothermal & Allied Technologies (AGGAT) is a HERA-led co-operative research programme to support the development of Organic Rankine Cycle (ORC) power plants utilizing low enthalpy geothermal resources or waste heat. The geothermal turbine, which converts the working fluid’s enthalpy into kinetic energy and then outputs the power, plays a crucial role in the…
