A new steel/concrete composite girder was proposed and applied to continuous girder bridges. The area surrounded by the upper and lower flanges and the web are filled with concrete (CFIG: Concrete filled I-section Girder) at the intermediate support.…

Steel in bridge construction in Australia has declined significantly over the last 40 years from around 25% of bridges to as low as 5% of bridges in recent years. The main reasons for this have been the proliferation of precast prestressed concrete…

This paper outlines the design of the replacement of the English Street Bridge over Tullamarine Freeway.

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…

In the last few decades, the use of carbon fibre reinforced polymer (CFRP) for strengthening structures has attracted structural engineers due to its superior properties, such as its high strength-toweight ratio, corrosion resistance and ease of…

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…
