Composite and Steel Construction compendium. Part 9: Light gauge steelwork

The various high performance concretes that might be used for concrete bridges, to make them either quicker and easier to build, or more economic are discussed. The advantages of high strength, lightweight, fibre reinforced and self-compacting concretes are described, together with the use of new materials that can replace steel for both reinforcement and prestressing.

This article looks at the concrete slab, considering the beam effective flange and how disruption to the concrete can be accommodated.

A new series from the Steel Construction Institute (SCI) begins with a look at the history of composite construction and the development of Eurocode 4.
