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…

Friction-type connections are widely used to connect steel members where slipping is not permitted under serviceability loads. The friction developed between the faying surfaces transfers the design shear forces at the serviceability limit states.…

Westgate Bridge is the largest bridge in Melbourne. The main span over the Yarra river is 336m long and made of a cable stayed steel box girder. The approach viaducts are made of prestressed concrete multicell box girders. The Western viaduct…

This paper describes a method by which quantification of physical damage to a pin mounting plate critical to a lifting span of a bridge can be carried out. These results are then used to form the basis of subsequent non-linear finite element…

Welding procedures have been developed for the repair and maintenance of wrought iron bridges. New qualification requirements are proposed that take into account the limited ductility of wrought iron yet allow an appropriate assessment of the…

Between 1871 and 1893, 27 wrought iron lattice truss road bridges were built in NSW. Of these, 17 were built under the guidance of the noted bridge designer John A. McDonald and the 16 remaining are managed by the NSW Roads and Traffic Authority…

Concrete deterioration due to reinforcement corrosion poses one of the greatest risks to the integrity of the Roads and Traffic Authority’s (RTA’s) bridge stock. As an alternative to Impressed Current Cathodic Protection (ICCP), the RTA is assessing…

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…

In June 2007, a severe storm over the Hunter Valley caused extensive damage to private and public infrastructure throughout the Hunter Valley. Moderate flooding caused damage to the abutments of the nominated bridges. The NSW RTA engaged the NSW…

Where road schemes require an alteration to alignment, width, or barrier containment standards on an existing bridge, the problems associated with achieving this are often significant. Records for bridges built more than 50 years ago are commonly…
