This contribution is a result of the researches, carried out by the authors as part of the SIXXI project - History of Structural Engineering in Italy in the 20th Century (ERC Advanced Grant, PI Sergio Poretti, Tullia Iori - www.sixxi.eu), about the transformation of Italian Engineering after the second half of the sixties. It reconstructs the evolution of the building systems introduced in the building sites of bridges and viaducts, from the presentation of industrial patents to the first applications abroad and then by national designers and companies, to examine what impact they had on the production of Italian engineering.

Designed for machines. Italian bridges and viaducts (1965-1990)
