Jürgen Stritzke

Jürgen Stritzke (born December 13, 1937 in Dresden ) is a German civil engineer and university professor.

Life

After attending secondary school in Dresden- Reick (since 1994 Julius-Ambrosius-Hülße-Gymnasium ) Stritzke studied civil engineering at the TH Dresden from 1955 to 1962 . Long before completing his studies, he advanced to become a welding engineer at the Central Institute for Welding Technology in Halle (1958), worked as an assistant at the chair of Gustav Bürgermeister (1906–1983) and wrote a thesis on orthotropic plates there .

Professional activities

Then Stritzke worked as a graduate engineer for the company Hünich & Löwe, Maschinen- und Stahlbau Dresden (today Maschinen- und Stahlbau Dresden - a subsidiary of the Herrenknecht Group ), where he was soon appointed collective manager for statics and construction and a number of special torsion and solved stability problems. Stritzke was well trained for this through the courses on statics, steel construction and stability given by Gustav Bürgermeister, the successor to Kurt Beyers (1881–1952) at the TH Dresden. But his interests in the challenges of reinforced concrete construction , especially prestressed concrete construction , were greater than those of steel construction. While the load bearing method still played a subordinate role in the Federal Republic of Germany , a paradigm shift developed by Willy Gehler (1876–1953) from elasticity to plasticity theory took place in reinforced concrete construction in the GDR in the early 1960s , which also spurred the emerging prestressed concrete construction. In particular, Gottfried Brendel (1913–1965) from the TU Dresden was a leader in the implementation of the design theory based on the load-bearing method in reinforced concrete construction (n-free design method). After Brendel's early death, Jürgen Stritzke continued his work in reinforced concrete research in the GDR.

In 1965 he was project manager at the Institute for Calculating Solid Engineering Structures at the TU Dresden. In 1966 he became an assistant at the chair for reinforced concrete and prestressed concrete construction at the TU Dresden, which was headed by Siegfried Schröder from 1969 to 1986. 1974 doctorate on the subject Stritzke a realistic acquisition of the stress and strain behavior of prestressed T-beams . he further deepened the subject of solid bridge construction in teaching and research he took over in 1987, in 1981 he became Facultas Docendi for solid bridge construction and in 1989 senior assistant. Stritzke has been a professor for solid bridge construction since 1992 and between 1992 and 1994 headed the management of the chair for reinforced concrete and prestressed concrete construction. Between 1997 and 2000 he was Dean of the Faculty of Civil Engineering and has been Emeritus since 2003 .

Jürgen Stritzke transformed and expanded the advantages of theory building in steel construction to the specifics of reinforced concrete construction. This is evidenced by his contributions to the theory of the plate beam, which he based on model tests and prepared in the form of aids for engineering practice.

Appreciation

Of the around 100 publications by Jürgen Stritzke, his co-authorship of the 19th, completely revised edition of the book founded in 1925 by Benno Löser (1878–1944) is in particular. to highlight. An early contribution to the historiography of structural engineering is Jürgen Stritzke's collaboration on the 1988 brochure on the work of Benno Löser, which had an expanded edition two years later . He also enriched the '' Bridge Handbook '' published by Gerhard Mehlhorn and Manfred Curbach . Many experts value Jürgen Stritzke for his council, but also for his dispute. So he joined the debate about the Dresden Waldschlößchenbrücke with verve .

Stritzke's greatest merit, however, is the Dresden Bridge Construction Symposium, which he initiated in 1991, which takes place every year at the beginning of March at the TU Dresden and has for many years developed into the top address for the supreme discipline of structural engineering in Central Europe, in which engineering practice is combined with civil engineering Meet clients and the next generation of students. His annual follow-up report on the Dresden bridge construction symposium in the journal Stahlbau can be regarded as a comprehensive status report on German bridge construction in a concise form.

Honors

In 2005, Jürgen Stritzke received the Dresden Congress Award from the mayor of his hometown for his services as Spiritus Rector of the Dresden Bridge Construction Symposium . Five years later, the Federal Chamber of Engineers (BIngK) awarded him the Medal of Honor at the 20th Dresden Bridge Construction Symposium for his commitment to the BIngK series “Landmarks of Civil Engineering in Germany” founded in 2007. Jürgen Stritzke received another medal of honor from his alma mater . As part of the 29th Dresden Bridge Construction Symposium on 11./12. March 2019, the Chamber of Engineers Saxony awarded Jürgen Stritzke with the Wackerbarth Medal.
