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…

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…

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 Ngauranga Interchange is located at the intersection of two State Highways that provide the only highway access from the surrounding regions to the city of Wellington, New Zealand. Reinforced Earth® walls retain the seaward side of the off-ramp…

The Bailey bridge system was originally invented for military usage during World War II. Since then, it has been used to meet emergency or temporary bridge needs. It has also been widely used as a permanent solution for pedestrian and road bridge…

Sydney’s ANZAC Bridge was recently the subject of a maintenance project which addressed four main areas to improve the future performance of the structure. These areas were: stay cable improvements
