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.

This article discusses the 375m long incrementally launched bridges over the Usuthu River using reinforced concrete, with no pre-stressing, to carry the construction stage loads.

Mainmark are introducing the STRAAM system of full scale structural integrity assessment and continuous monitoring for Bridges into Australia and New Zealand. Advances in measuring extremely low amplitude vibrations combined with methods for…

All reinforced concrete structures deteriorate over time. Corrosion of reinforcement is a major challenge to the durability of concrete structures. Corrosion in certain environments, such as marine, can compromise the durability of concrete and…
