- Abstract
In 1903 the French engineer Eugene Freyssinet realised that if an initial compressive force was applied to a reinforced concrete beam it would neutralise the tensile forces that would develop in the beam when it was subjected to a bending force.
It was not until the 1930's that this idea was developed to create prestressed concrete. This allowed the use of less material, higher strength steel reinforcing and prevented cracking of concrete occurring under load. As well it allowed longer spans for bridges and other structures.
This talk looks at the spread of this new technology from France, Germany and Belgium to the rest of Europe, the U.S.A. and the rest of the world.
The focus of the talk will look at the development of prestressed concrete from 1950 through to 1980 & compare its use in Australia & Denmark.
Early uses of prestressed concrete, in Australia, were in the construction of the Narrows Bridge in Perth, the Gladsville Bridge in Sydney & the Opera House.
