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/…

The New Zealand Transport Agency (Transport Agency) has recently published ‘Protective Coatings for Steel Bridges: A Guide for Bridge and Maintenance Engineers’. This was prepared by the authors to optimise the long-term capital and maintenance…

Case studies of bridges located in the Lockyer Valley in Queensland and the Solomon Islands are presented in the paper. Historically these locations have experienced extreme flooding. Flood damage at bridges can isolate communities and result in…

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…

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…

Australian steel standards have stringent requirements in regard to product conformity. According to Australian structural steel standards, the acceptance of steel is conditional on the evidence of compliance provided in rigorous mill test reports/…

This paper describes the changes made to two of the Australian Standards, AS/NZS 2312:2002 – ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings’ and AS 2832.1:2004 – ‘Cathodic protection of…
