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 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 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 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…

The existing rail lines at this location sit on a marginally stable embankment of 1.5:1 slope and height varying between 6m to 15m. The existing lines cross the M2 motorway via an under-bridge and Devlin’s creek via an old masonry arch culvert.

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…

A new steel/concrete composite girder was proposed and applied to continuous girder bridges. The area surrounded by the upper and lower flanges and the web are filled with concrete (CFIG: Concrete filled I-section Girder) at the intermediate support.…

The span length and general size of bridges across the Queensland road Network have increased substantially in recent years. This has led to the development of larger girder section sizes, along with the requirement to provide increased amounts of…
