Call for interest – Fabrication & installation of rig materials

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…

New Zealand engineering firm riding on the crest of wave energy – EHL Group

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…

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…

web-post-buckling-cellular-beam

Resource – Fire protection of beams with web-openings

Beams with web openings can include cellular beams fabricated from rolled sections or plate girders with circular or rectangular openings cut in the webs. Typical long-span floor beams of this nature are designed to act compositely with the floor slab, which greatly increases their load carrying capabilities. Authored by Prof. R Mark Lawson of Surrey…
