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…

As bridges age and standards evolve, it has become increasingly necessary to strengthen existing bridges as a much cheaper option than replacing bridges as a whole.

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…

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…

Timber bridges are enjoying a revival around the world for pedestrian and vehicular use. There are several reasons for this. Growing interest in reducing CO2 emissions and increasing sustainability has paved the way in part. New and innovative use…

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…

Cast iron was extensively used in bridge piers in early metal bridges in Australia. These cast iron bridge piers have performed well against atmospheric corrosion. However, the portion immersed in water suffers from graphitic corrosion, a form of…

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…
