Bonded Anchors: A VicRoads Perspective
Bonded Anchors are a type of connection which comprises a metal component, either a length of reinforcing bar, a threaded bar or a purpose-made anchor in combination with an adhesive. This type of anchor is increasingly being used to connect road-…
Rectification of Captain Cook Bridge Bearings
Captain Cook Bridge is an iconic bridge crossing the Brisbane River, and is the most trafficked bridge in Queensland, connecting the City’s south with the Brisbane Central Business District (CBD).
AS(AS/NZS) 5100 - 2017: Rail Bridge Design and Ratings - Key Changes
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…
Reducing Life-cycle Costs for Bridge Owners by Increasing Durability of the Bridge Bearing
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.

Wigram-Magdala Link Bridge: Low-Damage Details For a More Efficient Seismic Design Philosophy
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,…
Criteria and Guidance for the Design of Integral Bridges
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…
Assessment of Existing Composite Bridges
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…
Thermal Movements of Tasman Bridge
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…
Design Guidelines for Post-Installed and Cast-In Anchors in Australia for Safety-Critical Applications
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…
