Alkali activated binders (geopolymer) is an emerging technology to produce concrete without the use of any Ordinary Portland Cement (OPC) by alkali activation of alumino-silicate source materials such as fly ash and/or slag. Limited knowledge on…

Steel became a common construction material for bridges, replacing timber and masonry construction to achieve longer span crossings. These structures are still functioning well, although the majority of them are now considered to have sub-standard…

Strengthening-By-Stiffening (SBS) is a new concept developed to enhance the strength and performance of shear-deficient thin-walled steel girders. In SBS, pultruded composite sections are bonded to buckling prone web panels to serve as stiffeners.

Standard design techniques for corrugated steel culverts take advantage of the flexibility and ductility of the steel liners to transfer soil loads mainly through axial compression, with very small bending moments, relative to the size of the…

Roads and Maritime Services currently manages about 5600 bridges and bridge size culverts in New South Wales (NSW). These bridges were built during the last 150 years for various design loadings, structural forms and materials. Some of these bridges…

The occurrence of fires on bridges usually has a low probability but it has a high impact on the economic and social aspects. However, bridge design codes and standards do not explicitly incorporate fire safety concepts in design stage which is in…

The New Zealand Transport Agency (Transport Agency) has recently published ‘Protective Coatings for Steel Bridges: A Guide for Bridge and Maintenance Engineers’. This was prepared by the authors to optimise the long-term capital and maintenance…

Australian steel standards have stringent requirements in regard to product conformity. According to Australian structural steel standards, the acceptance of steel is conditional on the evidence of compliance provided in rigorous mill test reports/…

This paper describes the changes made to two of the Australian Standards, AS/NZS 2312:2002 – ‘Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings’ and AS 2832.1:2004 – ‘Cathodic protection of…

Recent changes to the Australian and New Zealand Standards AS/NZS 1163:2009 Cold-formed structural steel hollow sections, AS/NZS 3678:2011 Structural steel Hot-rolled plates, floorplates and slabs, AS/NZS 3679.1:2010 Structural steel Hot-rolled bars…
