François Hennebique

François Hennebique ( born April 25, 1842 in Neuville -Saint -Vaast ( Pas -de- Calais ), † March 20, 1921 in Paris) was a French civil engineer, who was one of the pioneers in the use of iron and reinforced concrete. His " system Hennebique " has also been adopted in Germany by licensing to construction companies by Eduard Züblin and Max Pommer.

Biography

After an apprenticeship as a stonemason in Arras he made himself independent in 1867 and launched in the same year, already the reconstruction of St. Martin in Courtrai. For two decades, ie from 1867 to 1887, he worked preferably in Brussels. In 1879 he applied for the first time in reinforced concrete.

In 1886, he suggested, mainly attributable to the tensile forces in the steel concrete reinforcing bars and the reported six years later for his first patent for reinforced concrete.

Two years later he was the first reinforced concrete bridge in Wiggen in Switzerland built. From 1896 he published the programmatic paper " Concrete armé ". Shortly before the turn of the century he was also involved in a project to design an Assuanstaudammes.

Hennebique was at the Paris World's Fair ( " Exposition Universelle et Internationale de Paris " ) 1900 known to a wide audience because of his important works in reinforced concrete construction. Already in 1892 he had developed the so-called T-shaped girder. But already in 1888 for a first concrete slab is called as a pioneer performance with such a bar. However, it was explained in 1903 his patent in 1892 for invalid to give the earlier patent by Joseph Monier in 1878 the preference.
