Karl Kordina

from Wikipedia, the free encyclopedia

Karl Kordina (born August 7, 1919 in Vienna , † August 14, 2005 in Braunschweig ) was a civil engineer born in Austria and later living in Germany .

Live and act

Kordina graduated from Vienna in 1937. From 1938 to 1941 he studied civil engineering at the Technical University in Vienna and then worked briefly as a bridge builder for the Reichsbahn. He took part in the Second World War as a soldier , was wounded, worked for the Reichsbahn again in the meantime and was finally taken prisoner in northern Germany. From autumn 1945 he worked as a civil engineer for various construction companies and an engineering office.

From 1953 he worked as a research assistant to Hubert Rüsch at the Institute for Solid Construction at the Technical University of Munich , where he received his doctorate in 1957 with a thesis on the load-bearing behavior of reinforced concrete columns.

In 1959 he was appointed to the chair of building materials science and reinforced concrete construction at the Technical University of Braunschweig as the successor to Theodor Kristen . In 1968 he took over the chair for solid construction there . From 1961, under his leadership, the establishment of a new institute for building materials, solid construction and fire protection with an affiliated official material testing institute for the building industry (from 1963) at the current location. He initiated the Collaborative Research Center 148 Fire Behavior of Components of the German Research Foundation , which he chaired as spokesman during its term from 1972 to 1986. He conducted full-scale natural fire experiments on a house in Lehrte and in a tunnel in Norway. In 1987 he retired. Even after retiring from active service, he continued to conduct research. After German reunification, he worked as a director at the materials research and testing institute for construction in Leipzig until 1997.

Kordina dealt in particular with the load-bearing behavior of reinforced concrete columns and frames, with stability problems ( buckling ), with shell structures , with prestressing and segment construction, with the fire behavior of components, with sound insulation , with safety theory, with corrosion issues, with concrete repair , with creep and shrinkage of Concrete as well as with the alkali-silica reaction of concrete.

Kordina was u. a. concerned with the following structures:

His main merits lie in a new dimensioning of slender reinforced concrete columns against buckling, implemented against strong resistance, taking into account the geometric and material non-linearities as well as fire protection. Kordina had a large share in standards in the field of reinforced concrete construction and fire protection and was a member of numerous national and international committees.

Kordina was married to the public prosecutor Brigitta Kordina and had several children.

Awards

Others

Kordina played the violin and viola. He was very committed to his employees, was known for his Viennese charm and at the same time feared for his temperament.
