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…

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…

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…

Detailed investigation and live-load evaluation was undertaken for several 1930s reinforced concrete bridges followed by strengthening where required.

NSW Roads and Maritime Services manage 26 movable span bridges of which 11 are still operational. These bridges were the subject of a recently completed study undertaken jointly by RMS and GHD Newcastle which focused on the components of each bridge…

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/…
