The use of bonded anchors to make structural connections to concrete surfaces of bridges and structural roadway components has been increasing steadily over the past 15 to 20 years due mainly to the flexibility in design, the ease and efficiency of…

A major revision of AS 5100.4 Bearing and Deck Joints has been undertaken in preparation for the publication of a new edition of AS 5100. The major changes to Part 4 of the Standard include the introduction of provisions for modular deck joints and…

Ideally, a balanced cantilever bridge is built with its superstructure continuous between the abutments. For long bridges, mid-length expansion joints may be necessary. The separation of expansion joints may be maximised by supporting the…

Modular bridge expansion joints (MBEJs) are widely used throughout the world for the provision of controlled pavement continuity during seismic, thermal expansion, contraction and long-term creep and shrinkage movements of bridge superstructures.…

Roads and Maritime Services of Transport for NSW in collaboration with the Bridge Solution Alliance formed by Freyssinet, Lend Lease and Sage Automation undertook a major maintenance project to solve stay cable vibrations, strengthening-related…

Melbourne’s West Gate Bridge, first opened to traffic in 1978, is around 2.5 km long and comprises an 848 m long five-span steel box girder portion over the Yarra River and two continuous concrete box girder approach viaducts 871 m and 670 m long.…

In modern bridge structures, bridge bearings and expansion joints are commonly the source of most maintenance and performance issues. In some situations their performance can lead to the closure/failure of major structures and their maintenance can…

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…
