Bridge Design Challenges on the Waikato Expressway Huntly Section, New Zealand
The Huntly Section is a new NZ$415M section of the Waikato Expressway running between Hamilton and Auckland. It will connect the recently completed Ngaruawahia and Ohinewai sections on a route that traverses the Taupiri Ranges within a deep cutting…
Analytical and Experimental Studies on New Composite Bridge Using Concrete Filled Steel I-girder
A new steel/concrete composite girder was proposed and applied to continuous girder bridges. The area surrounded by the upper and lower flanges and the web are filled with concrete (CFIG: Concrete filled I-section Girder) at the intermediate support.…
Fabrication and Erection of Structural Steelwork - The New AS/NZS 5131 and Engineers Risk Mitigation
This paper examines the initiative by the Australian Steel Institute to underwrite development of the new Australian Standard AS/NZS 5131 ‘Structural Steelwork – Fabrication and Erection’, the new ‘National Structural Steelwork Specification (NSSS)…

Across the globe, a huge sum is spent each year in maintaining and protecting steel infrastructure assets against corrosion. Most of the steel assets are protected using protective coatings or coating systems.
The Challenges Faced in Assessing the Durability Risks of Reinforced Concrete Bridges in Aggressive Environments
Durability assessment is increasingly becoming an integral part of infrastructure design projects in Australia. One of the key drivers for this is the requirement by asset owners for optimum whole of life cost, minimum construction period and…
The Use of Weathering Steel in Australian Bridges
Weathering steel is a high strength low alloy steel that, in a suitable environment, may be left unpainted due to the formation of an adherent protective rust “patina”. This patina significantly retards the corrosion rate, which is 5 to 10 times…
The Torsional Strengthening of Concrete Girders Using the NSM FRP Technique with Different Configurations
The near-surface mounted (NSM) FRP technique has received attention worldwide over the externally bonded FRP strengthening technique. Strengthening of a concrete girders using fiber reinforced polymer (FRP) composites to flexural and shear…
Fatigue Tests on Steel Plates with Inclined Cracks Strengthened with Different CFRP Properties
Carbon-fibre-reinforced-polymer (CFRP) strengthening of steel components with tensile cracks has gained significant attention in the civil engineering applications due to the advantages of the composite material in upgrading the performance level of…
Strength Enhancement of Fire-damaged RC Circular Bridge Columns using CFRP Fabrics
In recent years the circumferential wrapping with externally-bonded carbon fibre-reinforced polymer (CFRP) composites has proven to be a promising method for strengthening concrete structures. This is particularly valuable when repairing concrete…
Shear in Prestressed Concrete I-girder Bridges
Prestressed concrete I girder bridges constructed in the 1960s and 70s have the potential to restrict transport productivity because their AS 5100.7 assessments can be poor despite satisfactory inservice performance. The primary issue is the shear…
