From the book, Karl-Eugen Kurrer, The History of the Theory of Structures from Arch Analysis to Computational Mechanics, Ernst & Sohn, 2008:
“…the main condition was the development of stability theory, the transition from member to continuum analysis, composite construction theory and lightweight steel construction. Kurt Klöppel, who in 1929 took charge of the Technical-Scientific Department of the DStV, was elected managing director of the DASt in 1935 and appointed professor at Darmstadt TH in 1938, recognised this fact; he became chief editor of the journal Der Stahlbau one year later, a post he held until 1981.
His understanding of the fundamentals of structural steelwork was clearly emphasized in his presentation Rückblick und Ausblick auf die Entwicklung der wissenschaftlichen Grundlagen des Stahlbaues (review of and outlook for the development of the scientific basis of structural steelwork) [Klöppel, 1948, pp. 48 – 72] at the first DStV steelwork conference after the war (Hannover, 1947). Stability theory (buckling, local buckling, lateral buckling, torsional-flexural buckling), the transition from member to continuum analysis (beam grid, orthotropic plate), welding and materials science played the key roles.”
