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…

This paper discusses an agent-based framework for improved bridge asset management. The framework comprises a geospatial representation of a network, a bridge performance deterioration model, and behavioural models of key stakeholders.Effective…

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…

A key component to improving freight productivity in Australia is to improve access to the network for heavy vehicle operators. Assessment of bridge capacity is perceived to be critical to this aim.

There is significant pressure in Australia to improve freight productivity through the national reform agenda. A key component of the reform plan is to improve access to the road network for heavy vehicle operators. Assessment of bridge capacity is…

Performance modelling is an asset management tool used to quantify or qualify the performance of a bridge within the context of the overall bridge network. Performance modelling techniques include the use of performance indicators and deterioration…

This report develops approaches that estimate the marginal cost (MC) of bridge wear for heavy vehicle usage and estimates the availability and reliability of the data needed to use these approaches. Two approaches were examined. The first was an…

In modern bridge structures, bridge bearings and expansion joints are commonly the source of most maintenance and performance issues. In some situations their performance can lead to the closure/failure of major structures and their maintenance can…

Despite the fact that the occurrence of large earthquakes in Australia is rare, the consequences can be fatal and costly. The performance of bridges during and after earthquake events is critical in ensuring that road networks remain operational and…
