The two most advanced design guides on floor vibrations are SCI Publication 354 and CCIP-016 for steel-framed buildings and reinforced concrete buildings, respectively. Both design guides permit engineers to predict the response of structures due to human-induced vibrations to enable comparisons to be made with acceptance criteria contained within standards such as ISO 10137. Standards…

HERA members can you help? An essential objective of the AGGAT program under this research aim is the installation of a materials test rig on a geothermal site to investigate field-based geothermal scaling and corrosion. The data gathered in turn will accumulate into an industry owned information database to base future decisions on in terms…
For structural steel products to be free from serious problems in production and in service, it is necessary to provide a suitable level of quality management from the design phase, through material selection, into fabrication, and subsequently inspection. Requirements for welding/fabrication activities are given in the Code of Practice of the NZ Steel Fabricator Certification…
HERA member EHL provided the basis for US energy innovator Northwest Energy Innovations’ wave energy device, which was successfully deployed at the US Navy Wave Energy Test Site (WETS) near Kaneohe Bay, Oahu, Hawaii. The device, called Azura, will be deployed for 12 months of grid-connected testing as part of a rigorous programme to commercialise…
There is an increasing dialogue out in the market place about non-standard products being sold into the building and construction industry in NZ. The alleged numbers being reported are significant and almost somewhat unbelievable. But if they are anywhere near reality, we do need to be taking some form of action otherwise ‘Standards creep’ will…

Yesterday our member New Zealand Steel celebrated their 50 year anniversary. Forming an integral part of this country’s history for half a century. The company was formed on 26 July, 1965; steel production began in 1968 and major expansions were completed in 1987, creating an integrated steel mill. Located in Glenbrook, South West of Auckland,…
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…
In May 2015, Standards Australia senior management was alerted to the fact that the 2014 editions within the AS/NZS 1554 suite contained material that was included without adherence to Standards Australia’s standards development processes. The relevant material relates to specifications contained in the following standards: AS/NZS 1554.1:2014 Structural Steel Welding, Part 1: Welding of steel…
