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…

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/…

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 AS 5100 Standard provides requirements for multiple-performance-level barriers. Historical barriers constructed before 1970 generally do not meet modern requirements for safety. This paper builds on ongoing previous research projects within…

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…

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…

Consistency in the design of traffic barriers for bridges has been identified as a major issue in current practice throughout Australia and New Zealand. The need for standard solutions was recognised by road jurisdictions, consultants and…

The management of bridges as a key component in transportation infrastructure has become a major concern due to increasing traffic volumes, deterioration of bridges and well-publicised bridge failures. A critical responsibility for asset managers in…
