Karlheinz Roik (born September 5, 1924 in Frankfurt am Main ; † June 16, 2009 in Neuss ) was a German civil engineer ( steel construction ). He was an expert in composite steel construction .

biography

Roik was called up for military service in 1942, was seriously wounded and was briefly a prisoner of war. From 1945 he studied civil engineering at the TH Darmstadt, where he became a member of the Corps Hassia . He completed his studies in 1950 as a Dipl.-Ing. from. Kurt Klöppel was one of his academic teachers. He then worked for the steel construction company MAN Werk Gustavsburg , where he was involved in ten large bridges, including the Cologne-Rodenkirchen suspension bridge (assembly planning). In 1953 he became group leader at Dortmunder Union Bridge Construction. He used a six-week stay in hospital to write his dissertation and in 1955 he received his doctorate with distinction in Darmstadt. In 1955 he became department head at Neusser Eisenbau-Bleichert, where he was involved in around 20 bridges and large industrial halls. He introduced technical innovations (stud welding process for composite dowels for the flood bed bridge Mainz-Weisenau, new prestressing process for the Liedtal bridge). In 1963 he became professor for steel construction at the TU Berlin as successor to Konrad Sattler and in 1972 at the Ruhr University Bochum . He researched composite structures (in 1974, together with his students and employees, the guidelines for the dimensioning and execution of composite steel girders , which provided for the design according to the load-bearing method, were developed from this), introduced CAD techniques into steel construction and was significantly involved in Eurocode 4 (composite construction). In the 1980s he carried out tests on composite columns and was significantly involved in DIN 18806 (composite structures, composite columns).

He was a damage appraiser for the Danube Bridge in Vienna , the West Gate Bridge (partial collapse), the Auckland Harbor Bridge (defects) and the Hobart Bridge in Tasmania (ship impact, partial collapse).

In 1978 he co-founded the engineering office HRA (Haensel, Roik, Albrecht ) in Bochum, with whom he was involved in the Süderelbbrücke , the Fleher Bridge , the Werra Bridge near Hedemünde , the Sauertal Bridge and the widening and renovation of the Cologne-Rodenkirchen bridge. In 1997 he retired from HRA.

In 1988 he received the German Steel Construction Award and an honorary doctorate from the TU Berlin.
