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…

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…

Roads and Maritime Services NSW constructs many bridges over watercourses and the structural elements of these bridges are often exposed to a wide range of brackish water. Salinity levels of brackish water range from fresh drinking water to sea…

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…

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.

Infrastructure transportation systems play an important role in the sustained economic growth and social development of most countries. Bridges are key components in such systems. During their service life, bridges are subjected to progressive and/…

The south-west of Melbourne has experienced huge residential development, and a corresponding increase in rail patronage. The Regional Rail Project effected the separation of Regional and Metropolitan lines between Southern Cross Station, and…

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…
