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…

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…

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…

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…

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…

The new AS 5100.5 Concrete has been heavily revised since its last issue in 2004.

The current bridge design code, AS5100.5-2004, adopts concrete strength grades between 25MPa and 65MPa. The upper limit of 65MPa was an increase from 50MPa in the Austroads Bridge Design Code, 1992. Before that, the NAASRA Bridge Design…

The paper describes the development, design and construction aspects of a completely new precast, prestressed concrete girder for road bridges.
