biography

Reinitzhuber lost his parents at an early age and came under the guardianship of his maternal uncle Karl Federhofer , who was also a well-known civil engineer. He went to school in Graz (Bundeserziehungsanstalt Liebenau) and Wiener-Neustadt (Bundeserziehungsanstalt) with the Matura in 1927. He then studied civil engineering at the TH Graz , which he completed in the shortest possible time (9 semesters) in 1932. He got a job at the State Building Office of Styria and also worked on his dissertation, which was carried out in 1934 by Franz Brunner in Graz. The dissertation (displacement plans of spatial frameworks) used the graphic dynamics of his uncle Federhuber.

In 1936 he went to Humboldt-Deutz in Cologne and married in the same year. The marriage resulted in two daughters and a son. Among other things, he was involved in the design of a revolving zeppelin hall that was not realized and a bridge on the Lower Rhine. In 1938 he switched to the aircraft industry as a structural engineer at the Henschel company in Berlin-Schönefeld. He was involved in the development of the first aircraft that could fly 10,000 m high. From 1941 he worked in steel construction at the Reichswerke Hermann Göring , which was soon relocated because of the bombing of Berlin. Reinitzhuber came to Linz and during this time completed his habilitation with previously published work at the TH Graz.

After the war he worked in the successor company of the Reichswerke, the United Austrian Iron and Steel Works ( VÖEST ) in Linz as head of the technical office in steel construction. In 1950 he went to Egypt as a professor at the University of Alexandria through Hermann Beer . At the same time he taught steel construction at the Ain-Schams-University in Cairo and worked on bridge construction projects for Vöest. When he returned to Vöest in Linz in 1952, he became deputy operations director in steel construction. In 1957 he went to Krupp in Duisburg-Rheinhausen as technical director , which he stayed until 1967. He declined calls to the TH Vienna and the TH Stuttgart, but held regular lectures at the RWTH Aachen and the TH Graz from 1966 to 1980 .

His projects at Krupp included:

• Dos Americas Bridge, Panama Canal
• El Ferdan Bridge, Suez Canal
• Gothenburg harbor bridge
• Dismountable bridges for military and civil purposes
• Temporary flat steel roads for traffic diversion during construction work
• Parabolic mirror for radar
• Buildings such as Detmold District Hospital, Heidelberg Cancer Research Center, Osram administration
• Smelting works in Rourkela, for example
• Hydraulic steel construction such as the Henrichenburg ship lift

In 1968 he left Krupp and joined the engineering office of a fellow student (von Spieß) in Dortmund and was a test engineer for steel, wood and solid construction. He was also a sworn expert for steel construction. In 1980 he opened an engineering office in Dortmund with a new partner. Among other things, he checked the steel construction of the Wuppertal suspension railway, the Schermetjewo airport building in Moscow and Krupp steel works.

He was an honorary member of the German and Austrian Steel Association and the International Association for Bridge Construction and Building Construction.

In 1967 he bought a winery in Styria and expanded it.
