Konrad Sattler
Konrad Sattler (born September 28, 1905 in Köflach ; † October 17, 1999 in Graz ) was an Austrian civil engineer.
biography
Sattler was the son of a primary school teacher and headmaster and grew up in Graz. He studied civil engineering at the TH Graz, among others with Georg Kapsch , Karl Federhofer , Heinrich Neukirch (professor of statics and pioneer in the calculation of suspension bridges) and Bernhard Baule . In 1929 he passed both state exams with distinction and became an assistant to Franz Brunner . For his dissertation ( contribution to the buckling theory of thin plates ) in 1932 he used the difference method to solve the differential equations of the buckling problem in steel construction. He was also able to work with Brunner on the special design of a suspension bridge for the Reichsbrücke in Vienna (it won first prize in the competition). He then worked in the steel construction industry, initially in the bridge department of Gutehoffnungshütte in Duisburg-Sterkrade. One of the first tasks was to determine the natural frequencies of the suspension bridge over the Sava in Belgrade. After a year and a half he moved to the bridge construction company Hein Lehmann AG in Düsseldorf. In addition to bridges, he also designed buildings, hydraulic steel structures and pressure pipelines. He then worked for Krupp -Stahlbau in Duisburg-Rheinhausen , where he took over the bridge construction department as chief engineer with authority to act. The designs included a large suspension bridge over the Øresund and an unrealized swing bridge in Glove on Rügen, which would have been the largest in Europe. A road bridge with a swing bridge over the Nile near Samannūd was implemented , which earned it international recognition. The development of the SKR bridge (a dismountable bridge device for the German Reichsbahn with a span of up to 120 m) was of great importance. It was used a lot during World War II and in the reconstruction afterwards. In 1944 he was busy lifting the large arch bridge in Nijmegen when he was offered a position at the University of Graz.
In 1944 he succeeded Franz Brunner as professor for steel construction in Graz. Despite the advocacy of his colleagues, he was dismissed for political reasons in 1946. He went to the Ast company and developed a construction bridge based on the model of the SKR bridge device, which was used a lot in Austria. He also developed steel sliding formwork for double arched arch dams and designed reinforced concrete structures. With Adolf Pucher he developed the Sattler-Pucher assembly method. In 1951 he became professor for steel construction at the TU Berlin , where Franz Dischinger brought him. There he also dealt with prestressed concrete and in 1953 published the first monograph on composite structures (in the greatly expanded second edition from 1959, also including prestressed concrete). He examined the plastic behavior of composite and steel structures, the spatial stress state (elastic and plastic) and problems in the theory of the second order. He also expanded the Guyon-Massonet method for the calculation of support grids. In 1957/58 he was dean of the Faculty of Construction.
From 1962 he was a professor of structural engineering (as the successor to his friend Ernst Chwalla ) and steel construction. In 1965/66 he was dean of the Faculty of Civil Engineering and Architecture. 1967/68 he was rector of Graz University of Technology . He turned down an offer from Friedrich Krupp Maschinen- und Stahlbau in Rheinhausen to join the management.
He was editor of the journal Der Bauingenieur .
