The LH Ford Bridge, built in the 1960's, comprises 28 spans, is 800m long and crosses the Macquarie River at Dubbo, NSW. The main bridge spans comprise three spans with a 63m centre span (25m drop-in section) supported by halving joints from the…

Traditional inspection procedure for condition assessment of bridge structures is laborious, dangerous, time-consuming, capital intensive and highly dependent on subjective human judgment. Subsequently, bridge asset owners pay a high price per…

This paper will give a brief history of our concrete technology and concrete durability journey within TMR QLD over the last 20 years together with our present position and issues, and where we see some of our future challenges and development.…

Bridges in seismically active regions must be designed and constructed with special considera- tion of how the structure will respond/perform during an earthquake and immediately afterwards. A key element in such considerations is the expansion…

The potential benefits of using structural health monitoring systems in measuring and recording bridge data have been established in many applications around the world, but the efficiency and effectiveness of such systems depends on how they are…

Asset owners are interested in the use of durable concrete to maximize design life of their structures and minimize Whole of Life Cost (WOLC) throughout. Similarly, most assets owners nowadays also require their assets to be sustainable and…

Over recent years there have been a number of incidents of structural failures of sign and high mast lighting structures across Australia and New Zealand, primarily due to poor design and construction practices. In addition to the obvious…

State Highway 2 Wairoa River Bridge near Tauranga, constructed in 1966, is a 177m long post-tensioned concrete structure with mono pier columns supported on pile foundations. Adding a lightweight downstream cycleway extension in September 2020 has…

Outputs from bridge assessment to AS 5100.7 are deterministic, expressing safety as a subjective and conservative binary (yes/no) measure. With Australia and New Zealand seeing increases of road freight demand under finite bridge infrastructure…

Evidence gathered on some Queensland bridges has raised questions about what heavy vehicles are really doing to bridges. Visual evidence includes the deterioration of concrete bridge decks, headstock cracking, fatigue cracking, settlement of bridge…
