Heinz Duddeck

from Wikipedia, the free encyclopedia

Heinz Duddeck (born May 24, 1928 in Sensburg ; † August 18, 2017 ) was a German civil engineer.

Life

After escaping from East Prussia, doing military service and being a prisoner of war (until 1945), he began an apprenticeship as a bricklayer in Rastede (journeyman's examination in 1948), graduated from high school and studied civil engineering at the TH Hannover from 1949 to 1955 under Wolfgang Zerna (and H. Kauderer). He was also on a study visit to the University of Bristol . He was an assistant at the chair for steel construction and received his doctorate in 1959 (The edge fault problem of the technical bending theory of thin shells in three corresponding representations) . He then spent several years at Stanford University on a grant from the National Academy of Sciences . In 1963 he completed his habilitation at the TH Hannover (The Asymptotic Bending Theory of General Rotation Shells with Weak Variability of the Shell Curvature) . He then worked in the construction industry in Bern and in Concrete and Monierbau in Düsseldorf . In 1966 he became a full professor and director of the Institute for Statics at the Technical University of Braunschweig (inaugural lecture: What does the shell theory do? ). In 1996 he retired.

In addition to shell theory and surface structures (such as mushroom cover), he dealt with tunnel construction (but also statics, e.g. of salt caverns or for studies on underground nuclear power plants). The projects in which he was involved include the Elbtunnel (1966, 1985), the tunnels of the new Hanover – Würzburg line of the Deutsche Bundesbahn (1979 to 1990), the Emstunnel Leer and the BEWAG tunnel under the Spree (1995). He also dealt with the social responsibility of engineers and generally with design and computation models of engineers.

From 1979 to 1990 he was a member of the Civil Engineering Study Reform Commission.

For a long time he was on the scientific advisory board of the Daimler and Benz Foundation.

In 1988 he received an honorary doctorate from the University of Karlsruhe. In 1978 he became a member of the Braunschweig Scientific Society , in 1993 of the Academia Europaea and in 2002 of the Acatech . He was also a founding member of the Berlin-Brandenburg Academy of Sciences .
