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…

The existing rail lines at this location sit on a marginally stable embankment of 1.5:1 slope and height varying between 6m to 15m. The existing lines cross the M2 motorway via an under-bridge and Devlin’s creek via an old masonry arch culvert.

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…

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…

KiwiRail manages a wide range of rail assets, including approximately 1700 bridges and major culverts within resource and investment constraints. With an existing asset stock that is aging there is increased pressure to manage assets on whole-of-…

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…

A major revision of AS 5100.4 Bearings and Deck Joints has been undertaken in preparation for the publication of a new edition of AS 5100. The elastomeric bearing performance tables have been revised to make bearing selection easier and the movement…

This paper reports an independent study on the effects of Melbourne trams and Sydney light rail, and the heavy vehicle configurations defined in the draft AS5100.7 code on short to medium span bridges.

Expansions joints can be defined as a component of a bridge providing a continuous surface across the expansion gap for all classes of road users whilst accommodating all ranges of movements. Typically expansion joints are installed between adjacent…
