Durability assessment is increasingly becoming an integral part of infrastructure design projects in Australia. One of the key drivers for this is the requirement by asset owners for optimum whole of life cost, minimum construction period and…

Part 2 Design loads of Australian Standard AS 5100 Bridge design sets out the parameters for loads on all bridges in Australia. There have been numerous enhancements to improve the scope, clarity and intent. Design loads for road traffic barriers…

The near-surface mounted (NSM) FRP technique has received attention worldwide over the externally bonded FRP strengthening technique. Strengthening of a concrete girders using fiber reinforced polymer (FRP) composites to flexural and shear…

AS 5100 is the only Australian standard specific to bridges. For the first time, the scope has been extended from primarily a structural design standard to include other bridge related topics including safety-in-design, climate change and…

The revision of AS(AS/NZS) 5100 series has resulted in key changes to the provisions for train braking loads, dynamic load allowance, train collision loads, bridge bearings and design for light rail bridges. Longitudinal rail force provisions have…

The Huntly Section is a new NZ$415M section of the Waikato Expressway running between Hamilton and Auckland. It will connect the recently completed Ngaruawahia and Ohinewai sections on a route that traverses the Taupiri Ranges within a deep cutting…

The Torrens Road to Torrens River (T2T) project forms part of the overall North-South Road Corridor upgrade in Adelaide, South Australia and incorporates many components such as a new lowered motorway, road, service and pedestrian bridges, retaining…

Four bridges in the Fiji Islands were recently replaced using a Design and Construction procurement method for the Fiji Road Authority. The bridges provided vehicle, pedestrian and Fiji Sugar Corporation cane trains over waterways subjected to…

In recent years the circumferential wrapping with externally-bonded carbon fibre-reinforced polymer (CFRP) composites has proven to be a promising method for strengthening concrete structures. This is particularly valuable when repairing concrete…

Prestressed concrete I girder bridges constructed in the 1960s and 70s have the potential to restrict transport productivity because their AS 5100.7 assessments can be poor despite satisfactory inservice performance. The primary issue is the shear…
