Evaluation and Strengthening of Existing Bridges to Carry Increased Vehicle Weights
Detailed investigation and live-load evaluation was undertaken for several 1930s reinforced concrete bridges followed by strengthening where required.
Movable Span Bridges of NSW: A New Classification System
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…
Time-Variant Performance Indicators for Concrete Bridges Exposed to Corrosion
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…
Lifetime Performance, Risk and Sustainability of Bridges
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/…
Long-Term Performance of Concrete Bridges Under Extreme Events
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…
Seismic Assessment and Strengthening of Reinforced Earth Bridge Abutment and Approach Walls
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…
Life-cycle Management of Bridges: What is the Best Approach?
A key element of optimised asset management involves determining the type and timing of maintenance and renewals actions to achieve the least whole-of-life cost. This can often be a very complex process in reality because of the many different…
Condition Assessment and Load Rating of Arched Bailey Bridge
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…
Anzac Bridge Maintenance Project: Bridge-Specific Assessment of Live Load
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
Bridge Widening on Auckland’s Causeway Upgrade
The State Highway 16 Causeway Upgrade Project forms one section of the NZ Transport Agency’s Western Ring Route around Auckland, which is due to be completed by early 2017. The project improves, widens and raises approximately 4.8 km of motorway,…
