The revision of AS(AS/NZS) 5100 series has resulted in key changes to the provisions for train braking loads, dynamic load allowance, train collision loads, bridge bearings and design for light rail bridges. Longitudinal rail force provisions have…

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…

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…

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…

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…
