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…

KiwiRail manages a wide range of rail assets, including approximately 1700 bridges and major culverts within resource and investment constraints. With an existing asset stock that is aging there is increased pressure to manage assets on whole-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…

This paper reports an independent study on the effects of Melbourne trams and Sydney light rail, and the heavy vehicle configurations defined in the draft AS5100.7 code on short to medium span bridges.

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.
