In late 2014 Austroads sought feedback on a proposal to add two new specialist categories to Australia’s National Prequalification System.

A major revision of AS 5100.4 Bearing and Deck Joints has been undertaken in preparation for the publication of a new edition of AS 5100. The major changes to Part 4 of the Standard include the introduction of provisions for modular deck joints and…

Since the introduction of the current Bridge Design Standard in 2004 there have been real advances in both design and construction methods and in materials technology. The Part 5 Standards Australia Sub-Committee (BD090-05) has responded to this…

The life-cycle performance of concrete bridges exposed to corrosion is investigated based on a set of time-variant probabilistic performance indicators including structural reliability, redundancy, robustness and resilience. The performance…

Reinforced concrete (RC) structures in a marine environment deteriorate with time due to chloride-induced corrosion of reinforcing bars. Corrosion is initiated by chloride contamination if the structures have poor quality concrete and/or inadequate…

Ideally, a balanced cantilever bridge is built with its superstructure continuous between the abutments. For long bridges, mid-length expansion joints may be necessary. The separation of expansion joints may be maximised by supporting the…

The use of self-compacting concrete (SCC) in identified concrete bridge elements has now been incorporated in NSW Roads and Maritime Services QA Specifications B80 as Annexure B80/G. The use of SCC in precast elements is generally allowed while a…

In this paper a framework for assessing the robustness of existing reinforced concrete structures under corrosion is presented. Robustness is defined as a structural property related to the tolerance to damage and is measured by the mean performance…

The use of precast concrete for construction of bridge substructures offers a number of advantages over the conventional use of cast in place (CIP) concrete. These advantages include increased construction speed and quality, minimised traffic…

Australian bridge design code AS 5100.5 in Section 8.6.2 prescribes simplified criteria to meet the requirements for crack control applicable to a partially prestressed concrete beam. The incremental stress permitted in bonded reinforcement after…
