History
Eugène Freyssinet conceived the idea of Prestressing for the first time in 1903.
Three years later he issued a paper in which he described the elastic properties of concrete, which had previously only been known for steel. Freyssinet continued to develop the technique between 1903 and 1928 when a patent entitled the "Manufacturing process for reinforced concrete components" was taken out for the Prestressing system. The term "prestressing" did not appear until 1932. Freyssinet made a widely publicised demonstration of the advantages of Prestressing in 1934, by successfully consolidating the Le Havre shipping terminal.
In 1943, Edme Campenon, Chairman of Entreprises Campenon Bernard, created the STUP (Sociètè Technique pour l'Utilisation de la Prècontrainte - Engineering Company for the use of Prestressing), to take over and continue research work initiated by Eugène Freyssinet. STUP's continuing role was to promote prestressing techniques and their applications to clients, to manufacture prestressing equipment and materials, and to provide technical assistance on site. The history of the Freyssinet Group thus includes four main steps.
