birth Eugène Freyssinet Born 13 Jul 1879; died 8 Jun 1962 at age 82. Marie-Eugène-Léon Freyssinet was a French civil engineer who successfully developed pre-stressed concrete, that is, concrete beams or girders in which steel wire is embedded under tension, greatly strengthening the concrete member. The prestressing technique was devised to overcome difficulties in executing curved shapes in reinforced concrete. More an engineer than an architect, Freyssinet began creating innovative architecture using reinforced concrete as his main material, such as airship hangars at Orly Airport, France (1921), bridges and industrial buildings. His first use of pre-stressed concrete was for the renovation of the transatlantic pier at Le Havre (1933-35). |
