Weather Resistant Steel As Viable Option For Country Timber Bridge Replacements
Steel in bridge construction in Australia has declined significantly over the last 40 years from around 25% of bridges to as low as 5% of bridges in recent years. The main reasons for this have been the proliferation of precast prestressed concrete…

Local councils face the growing challenge, as road authorities, of maintaining and eventually replacing ageing bridges on regional and local roads.
Rehabilitation of Corrugated Metal Pipe Culverts: Asset management
VicRoads monitors a number of structures along its road networks through the structure monitoring program. In October 2014, VicRoads identified significant corrosion on two triple-cell corrugated metal culverts under the Mornington Peninsula Freeway…
Improved Bridge Deterioration Models, Predictive Tools and Costs
The management of Australia and New Zealand’s bridge stock involves the development of forward works programs for periods up to, and longer than, ten years into the future. The scheduling of maintenance, rehabilitation and replacement, forms part of…
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…
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…
An Agent-Based Framework for Improved Strategic Bridge Asset management
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…
Life-Cycle Management of Bridges Based on Robustness to Deterioration
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…
