Australia has regularly reviewed access to the road and bridge network with a view to increasing transport productivity. The current access regime for heavy vehicles has evolved over time with access now controlled by a range of regulations, notices,…

Over recent years, Public Transport Victoria through its operator Yarra Trams, has been gradually introducing new class trams (of which the E Class is the heaviest and longest) on Melbourne’s tram network.

The present study is concerned with the drift and displacement based seismic assessment of bridge abutments. This study is distinguished from previous research that has been reported in the literature in that what is of primary interests is the…

Theoretical assessments of a bridge network to AS5100.7 identify many bridges operating at margins smaller than those embodied in AS 5100.7. The cost of strengthening these bridges is unpalatable and the consequences of restricting access are…

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…

The change in title of the 2004 Australian Standard AS 5100 Part 7 Rating to the revised AS 5100 Part 7 Bridge Assessment is symbolic of the change of focus of this part of the standard. The 2004 version of the standard had an objective “to…

Grillage analogy is a popular method for analyzing various types of highway bridges in design offices. For load assessment of existing bridges in Australia, mainly beam line model and grillage analogy are employed to evaluate the structural…

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.

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…

Australia still has thousands of timber bridges in service which were designed and constructed long ago to carry lighter loads than they now carry. The Queensland Department of Transport and Main Roads manages in excess of 300 timber bridges, of…
