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…

Rapidly improving design technology and the desire to optimise structural designs, present challenges, and also opportunities, for bridge designers. One of the most important components of a modern bridge is the bearings.

The aftermath of the Christchurch earthquake highlighted difficulties in the assessment and repair of damaged plastic hinge zones in conventional reinforced concrete structures. Particular issues are uncertainty in strain history, low-cycle fatigue,…

Integral and semi-integral bridges are a common form of construction, providing some marked advantages over other construction forms. Integral and semi-integral bridges minimise the use of bearings and expansion joints by providing a direct…

Since the early 1920’s steel-concrete composite bridges have been widely used on New Zealand’s State Highway Network. Unfortunately, many shear connector types that have been used are not supported by current design rules within the standards…

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.…

Tasman Bridge crosses the Derwent River joining Hobart to its eastern suburbs. It was built in the early 1960’s and reflects design concepts of the time. It is articulated so that the main viaducts are restrained by the abutments, with very slender…

Steel in bridge construction in Australia has declined significantly over the last 40 years from around 25% of bridges to as low as 5% of bridges in recent years. The main reasons for this have been the proliferation of precast prestressed concrete…

Post-installed and cast-in anchors are commonly used in safety-critical applications in buildings and large infrastructure projects. This paper discusses the new Standards Australia Technical Specification TS 101:2015 which is the first Australian…
