Otto Jungbluth
Otto Jungbluth (born February 23, 1918 in Mannheim ; † January 26, 1995 in Darmstadt ) was a German civil engineer and university professor.
Live and act
After graduating from high school, Jungbluth worked as an intern on construction sites. The Reich Labor Service followed in 1938 and then military service in the Wehrmacht until the end of World War II . At the beginning of the first year of peace in 1946 he began studying civil engineering at the TH Darmstadt and graduated in 1949 with the diploma examination. Until 1953 Jungbluth worked as a scientific assistant to Kurt Klöppel at the chair for steel construction and statics and was awarded a doctorate degree from the TH Darmstadt with a dissertation on the structural analysis of guyed masts according to the second order theory . PhD.
From 1953 to 1963 Jungbluth worked for the Darmstadt steel construction company Donges, where he initiated some successful developments; An example is the Dolesta girder, a truss with thin-walled, cold-formed belts that were partially filled with concrete to increase stability. In 1963 he switched to Hüttenwerke Siegerland AG (from 1969 Hoesch -Siegerlandwerke AG), where as a member of the board he was responsible for the first continuous production of sandwich elements . At the 12th German Steel Construction Day in Aachen in 1964, questions of lightweight steel construction were the focus. In the Federal Republic of Germany lightweight steel construction thus increased on an industrial scale. With the industrial and residential construction, Jungbluth aimed to work on an increasingly important segment of the construction market, which he wanted to tap even better with the series production of prefabricated steel parts on automatic production lines for steel construction. The sandwich dome that still exists today on the exhibition grounds in Hanover comes from Jungbluth's creative period at Hüttenwerke Siegerland AG, which was then just being incorporated into the newly formed Hoesch Group. Although Jungbluth left his company during this restructuring process in 1967, he can be regarded as a protagonist of industrial science in the field of lightweight steel construction in general and sandwich construction in particular, after an interlude as a consulting engineer in Dortmund in 1969 at the Ruhr University, which was founded in 1967 Bochum (RUB), where he was able to continue his research on lightweight steel construction. a. inspired Helmut Bode's dissertation on sandwich panels.
In 1972 Jungbluth accepted the professorship in steel construction at the TH Darmstadt and developed an extraordinarily fruitful scientific activity there until his retirement in 1983. During this creative period, Jungbluth was responsible for 30 third-party funded research projects and 27 dissertations. He was in charge of Klaus Berner's dissertation on temperature stresses on sandwich panels. In 1986, with the support of Klaus Berner, Jungbluth published a standard work on lightweight steel construction on composite and sandwich structures. Jungbluth also did pioneering work in the field of integral planning in construction based on the first CAD systems in the Federal Republic of Germany.
In addition to his work in research and teaching at the TH Darmstadt, Jungbluth also volunteered. For years he was chairman of the German Committee for Steel Construction (DASt) and as such took over the management of the “Steel Construction” technical committee in the DIN construction standards committee.
A few weeks before he turned 77, Otto Jungbluth died on January 26, 1995 in Darmstadt.
