Armand Gabriel Considère (born June 8, 1841 in Port-sur-Saône , † August 3, 1914 in Paris ) was a French civil engineer. He is one of the pioneers of reinforced concrete .

biography

Armand Considère studied from 1860 at the École Polytechnique and then at the École nationale des ponts et chaussées . From 1865 he was in the Corps de Ponts et Chaussées with the first stationing in Morlaix . In the Franco-Prussian War he was an officer of the pioneers. In 1875 he went into the steel industry, from 1879 in Saint-Nazaire. From 1883 he was back in the civil service, from 1885 as chief engineer of the Finistère department, responsible for roads, hydraulic engineering, lighthouses and railways. In 1899 he published a contribution to the theory of reinforced concrete (dimensioning of beams with consideration of the concrete tensile strength). After the bridge passage built for the world exhibition over the avenue de Suffren to the Globe Céleste collapsed on April 29, 1900 with 9 dead, a commission for reinforced concrete was formed, whose main rapporteur was Considère. It was chaired by Théodore Lorieux and then by Jean Résal . By 1905 numerous experiments were carried out in three sub-commissions (one headed by Considère). In 1906 the French reinforced concrete regulations became official and published.

In 1901 he registered the strapped reinforced concrete column (béton fretté) for a patent, examined it through experiments with Augustin Mesnager (1862–1933) and put it through in practice. In 1902 he became inspector general for roads and bridges. In 1906 he opened his own engineering office. Albert Caquot was a partner in his office from 1912 .

He also made contributions to earth pressure theory (1870).

In 1892 he became a corresponding member of the Académie des Sciences .
