A Trans-Tasman success story for bridge design
The heavy engineering industry’s decision to harmonize bridge design with
Chaired by the Heavy Engineering Research Association’s (HERA) Structural Systems General Manager, Dr Stephen Hicks, DR AS/NZS 5100.6 provides greater alignment with international best practice and, in some cases, significant improvements for HERA’s members involved in bridge infrastructure projects. Dr Hicks says he sees this collaboration as a way to increase
Following international trends that call for using less natural resources, higher strength concrete with compressive strengths up to 100 MPa, and quenched and tempered steels with a yield strength of up to 690 MPa it was clear New Zealand’s existing standards needed improvement.
These higher strength materials went beyond the limits permitted in current international design standards, requiring many of the design provisions to be reassessed through structural reliability analyses to ensure the required margins of safety were maintained. Since 2011, HERA has worked extensively with the
At the same time, HERA’s New Zealand Welding Centre General Manager, Dr Michail Karpenko, worked with the renowned specialist expertise of Prof Adolf Hobbacher from the Wilhelmshaven University of Applied Sciences in
