These guidelines provide essential information regarding Buried corrugated metal structures (BCMS) from the design process, installation, in-service monitoring, through to maintenance and repair procedures. BCMS have been used in Australia as an…

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…

Modular bridge expansion joints (MBEJs) are utilised when the movement range at a bridge expansion gap exceeds around 300 mm, with the largest MBEJ installed to date accommodating a movement range in excess of 2100 mm. Traditionally MBEJs have been…

This paper deals with an experimental investigation of a new type of composite bridge using fully prefabricated concrete elements, which shortens the construction time and hence reduces production and economic costs.

Fingerplate bridge deck joints used worldwide to span medium to large expansion joint gaps are usually anchored to concrete decks with debonded through-bolts or sleeved bolts with embedded threaded ferrules. The current approach used by Roads and…

RTA’s bridge design engineers have identified that the current capacity reduction factors for cast iron specified in AS 5100.6 are inordinately low compared to those for other engineering metals such as structural steels and wrought iron. The…

A significant number of railway bridges within New South Wales are constructed from steel and have riveted connections which are forced to flex when transmitting loads through the structure. These connections are typically considered to have only a…

This paper presents a finite element analysis (FEA) of a composite pile with shear keys that transfer the load from concrete pier to steel pile with a lapping length. This piling system differs from most cast-in-situ piles in that the concrete is…

The Legacy Way tunnel, constructed by Transcity JV (Acciona / BMD / Ghella) for Brisbane City Council, will commence at the Western Freeway at Toowong and extend 4.6km to the northeast, joining the Inner City Bypass at Kelvin Grove. The mainline…

Cable-stayed bridges are currently the most attractive bridge type in the world. Their main spans cover a range from about 100m with one tower up to more than 1000m. Their intermediate construction stages are stable, because the flow of forces is
