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…
A Decision Support Model for Bridge Infrastructure Asset management
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…
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.
Sustainable Management of Installation of Impressed Current Cathodic Protection Systems for Bridges of the Future
The role of effective project/contract management in the successful delivery of Impressed Current Cathodic Protection (ICCP) systems has been recognised by RMS specification for ICCP, BS361, which has comprehensive provisions for the supervision 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…
Incorporating ACI 440.8 into AS 5100.5 for FRP Strengthening Via M80 Upgrade Project Case Study
As bridges age and standards evolve, it has become increasingly necessary to strengthen existing bridges as a much cheaper option than replacing bridges as a whole.
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/…
The New AS 5100 Part 8: Rehabilitation and Strengthening
AS 5100 was originally developed for the design of new bridges. There are however, approximately 20,000 existing bridges in Australia. Although Part 7 of the Standard relates to the strength rating of existing bridges, the existing AS 5100 generally…
The New Zealand Transport Agency Guide to Bridge Painting
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…
Climbing Robot for Steel Bridge Inspection: Engineering Challenges
Inspection of bridges often requires high-risk operations such as working at heights, in confined spaces, in hazardous environments, or sites inaccessible by humans. There is significant motivation for robotic solutions which can carry out these…
