About Change this

Anghel I. Saligny, an academician, engineer, construction engineer, minister and teacher, is considered to be one of the pioneers of world technology in the designing and construction of bridges and silos with metal structure and reinforced concrete, one of the founders of Romanian engineering.

Anghel Saligny was born on April 19, 1854, in Şerbăneşti commune, Galati county and died on June 17, 1925, in Bucharest. He attended the first school classes at the children's boarding school in Focsani, founded by his father, Alfred Saligny, a teacher of French origin in Alsace, established in Romania, then attended secondary education at the gymnasium in Focsani, Unirea National College, from the same locality , and then high school in Germany in Potsdam. Being initially attracted to astronomy, he attended the courses of the University of Berlin, having as a professor the famous physicist Hermann von Helmholtz (1821-1894).
Between 1870 and 1874, he studied engineering at the Upper Technical School in Charlottenburg, where Schwedler and Franzius engineers were illusory teachers. He worked under the supervision of Professor G. Mehrtens in the construction of the Cottbus-Frankfurt railway on Oder and, under the direction of Gheorghe Duca (between 1877 and 1879), in the construction of the Ploiesti-Predeal railway.

Between 1884 and 1889 he worked on the construction of the docks and warehouses in Galaţi and Braila, giving total original solutions, including: the construction of foundations on fascination layers and pile drivers, the connection basins with the Danube for silos and the use, for the first time in the world, reinforced concrete in silos construction.
Based on his own inventions, Anghel Saligny built for the first time the reinforced concrete silos from Braila (1888) and Galaţi (1889), only two decades after the French Joseph Monier (1823-1906) obtained in 1867 , the first patent for building elements (beams, slabs, pillars) of reinforced concrete, this material little studied at the time. The silos designed and executed, under the direct guidance of Anghel Saligny, could contain over 25,000 tonnes of grain (30 m x 120 m at the base and over 18 m tall). The hexagonal cell walls of the silos have been made, for the first time in the world, by plate-shaped pieces made to the ground. Prefabrication of floorboards, stiffening and junction corners, metal strip welding and assembly-based assembly are other global priorities.
His most important work is the design in 1888 and the construction of the Cernavoda Danube Bridge, which at that time was the longest in Europe and among the most important metallic openings in the world, between 1890 and 1895. Saligny's project brought two major innovations in the construction of bridges: the new beam system with consoles for the bridge superstructure and the use of soft steel instead of puddle iron as building material for bridge bridges.
Between the years 1889 and 1909 he headed the Constanta harbor works, introducing for the first time in Romania pilots and artillery dredgers in the port constructions and designing the grain silos and the oil station.
