Josef Eibl

from Wikipedia, the free encyclopedia

Josef Eibl (born March 22, 1936 in Parsberg ; † September 4, 2018 ) was a German civil engineer.

Life

Eibl studied civil engineering at the TH Munich from 1954 to 1959 and was then assistant to Hubert Rüsch at the chair for solid construction. After a short time at the construction company Karl Stöhr in Munich, he went to Karl Kordina at the Technical University of Braunschweig , where he received his doctorate in 1963 ( on the stability issue of the two-joint arch with flexible drawstring and slack hanging rods ). He then worked for four years in the construction industry, including group leader at Dyckerhoff & Widmann in Nuremberg. Eibl completed his habilitation in 1968 with the text On the application of conformal images in membrane theory for shells according to surfaces of the 2nd order with positive Gaussian curvature and became a professor at the TU Braunschweig (Institute for Building Materials, Solid Construction and Fire Protection). From 1970 to 1974 he worked for Dyckerhoff and Widmann and for the engineering office Leonhardt, Andrä and Partner in Stuttgart. In 1974 he became full professor for statics and structural mechanics at the University of Dortmund and in 1977 professor for concrete and reinforced concrete construction in Dortmund. In 1982 he became professor for solid construction at the University of Karlsruhe .

Act

Among other things, he dealt with the processes involved in emptying silos and with dust explosions (subject of a Collaborative Research Center in Karlsruhe), reinforcement of reinforced concrete with shotcrete, rotation of reinforced concrete structures, dimensioning of beams, columns and slabs for impact loads. Since the mid-1980s he campaigned for external prestressing in bridge construction with prestressed concrete, with which he established himself in Germany, and for segment construction. He also dealt with reactor safety (structural measures to increase safety after a meltdown). This was part of the so-called Karlsruhe security concept (with Hans-Henning Hennies and Günther Keßler), which was presented in 1989. The concept was received with reservations at the time, as it had not been discussed with either industry or the Federal Ministry of Research. In further work, Eibl showed, among other things, that the high pressure (short-term support forces up to 340 MN) in the event of a core meltdown and the demolition of the lower spherical cap of the reactor pressure vessel could be counteracted by constructive (passive) measures. At that time, however, the safety concept hardly met with any response; it was generally of the opinion that core meltdowns should fundamentally be excluded in the design of the reactor.

From 1991 to 2002 he published the concrete calendar .

Honors

In 1999 he received the Emil Mörsch Memorial Medal and the fib Merit Medal. He is an honorary doctor from the TU Dresden and the University of Innsbruck . Eibl has been awarded the Federal Cross of Merit on Ribbon of the Order of Merit of the Federal Republic of Germany .
