These guidelines provide essential information regarding Buried corrugated metal structures (BCMS) from the design process, installation, in-service monitoring, through to maintenance and repair procedures. BCMS have been used in Australia as an…

The Howe truss was patented in USA initially in 1840 and again in 1850 and went on to become one of the primary timber truss designs used in North America. The adaptation of the Howe truss in NSW into the two distinct forms known as the “Allan” and…

Great advances have been made in modular expansion joint technology since this most versatile type of joint was invented forty years ago, and the use of such joints, especially on very large bridges, has increased steadily. As a consequence,…

A Consortium of the Welding Technology Institute of Australia (WTIA) members consisting of Australian Rail Track Corporation (ARTC), RailCorp, Roads and Traffic Authority of New South Wales (RTA), and Transport Main Roads (TMR), Queensland has…

The paper summarizes laboratory tests carried out by RTA Bridge Engineering to investigate different factors affecting the reliability of bolted connections for bridge deck expansion joints. The test rig comprised steel plates bolted to a large…

Modular bridge expansion joints (MBEJs) are utilised when the movement range at a bridge expansion gap exceeds around 300 mm, with the largest MBEJ installed to date accommodating a movement range in excess of 2100 mm. Traditionally MBEJs have been…

The 2.5km long West Gate Bridge comprises an eastern and western concrete approach viaduct, 871m and 670m respectively in length either side of the 850 m long cable stayed steel box girder main span section. The key objective with the West Gate…

The main structural components of the railway bridge at Bankstown, installed in January 2011, are two 18m steel welded arch trusses with an overall height of 3.5m. Each truss comprises fabricated box sections for the chords and I sections for the…

This paper deals with an experimental investigation of a new type of composite bridge using fully prefabricated concrete elements, which shortens the construction time and hence reduces production and economic costs.

Fingerplate bridge deck joints used worldwide to span medium to large expansion joint gaps are usually anchored to concrete decks with debonded through-bolts or sleeved bolts with embedded threaded ferrules. The current approach used by Roads and…
