Recent changes to the Australian and New Zealand Standards AS/NZS 1163:2009 Cold-formed structural steel hollow sections, AS/NZS 3678:2011 Structural steel Hot-rolled plates, floorplates and slabs, AS/NZS 3679.1:2010 Structural steel Hot-rolled bars…

The Auckland Harbour Bridge (AHB) is a steel truss bridge with welded orthotropic box girder extensions on both sides and provides a critical link over the Waitemata harbour. The logistical layout of the surrounding area does not provide any other…

Corrosion damage of steel elements is the main driver for development of corrosion management strategies by Asset Managers, the implementation of which draws significant amount from the government treasury. Since economic viability of any project is…

Inorganic zinc silicate coatings have been an attractive coating for steel bridges due their excellent long-term corrosion protection extending for up to 40 years. The re-coating of inorganic zinc silicate coatings has been regarded as a difficult…

It is essential bridge infrastructure projects be constructed from materials conforming to the relevant standard. Historically, Australian Standards have detailed the performance criteria in construction products are required to achieve, but…

Reinforced concrete made its way into road bridges at the start of the twentieth century after being invented by Joseph Monier in 1875. By 1950 reinforced concrete was dominant for small and medium spans and vying with steel for longer spans. Their…

One of the most significant breakthrough developments in concrete technology at the end of the 20th century was that of ultra-high performance ‘ductile’ concrete (UHPdC) with compressive strength up to 200 MPa and remarkable improvements in…

The Sulfate-resisting concrete is traditionally specified by cement type and concrete mix proportions in terms of maximum water-cement ratio and/or minimum cement content.

A wide range of test methods has been used to measure the resistance of concrete to chloride penetration. Each method is purported to measure the property of concrete central to the chloride transport mechanism into concrete. They include water…

One of the key elements underpinning sustainable bridges is innovation in the use of materials and technology in the area of Bridge Engineering. Any innovation requires validation through measurable outcomes.
