Klaus Brandes

Klaus Brandes (born November 7, 1936 in Insterburg ) is a German civil engineer and lecturer.

Live and act

Brandes completed a civil engineering degree at the TU Berlin from 1956 to 1964 . He then worked until 1968 at the chair for steel construction with Karlheinz Roik as a scientific assistant and in 1968 received a doctorate in the field of shell theory from the Technical University of Berlin to become a Dr.-Ing. PhD. István Szabó , with whom Brandes worked for several years as an assistant, acted as co- reporter.

In addition to Roik and Szabó, the director of the Federal Institute for Materials Research (BAM), Thomas A. Jaeger , was one of Klaus Brandes' teachers. In 1968 he became his employee and from 1976 headed laboratories including those for structural dynamics, that for steel construction and finally that for structural safety. At that time, Jaeger developed BAM into the center of nuclear engineering, a sub-discipline of structural engineering , which can be considered one of the rare examples of so-called big science in the field of civil engineering and which attracted numerous talented engineers. Brandes worked, among other things, within the framework of the R&D program on prestressed concrete - reactor pressure vessels of the federal government at BAM under the direction of Jaeger.

After Jaeger's early death in 1980 and the withdrawal of state research funding from nuclear energy, Brandes turned step by step to topics from structural safety and steel construction. Inspired by discussions with specialist colleagues from the field of mechanical engineering and as a late response to the scientific penetration of reactor construction, Gert Albrecht and Brandes introduced fracture mechanics considerations for the first time in the Federal Republic of Germany when examining structural parts in riveted bridges subject to fatigue. With his fatigue tests on trusses of the Berlin underground line U1 , Brandes supports the efforts of Werner Lorenz to largely preserve the supporting structures of the U1 by upgrading them in accordance with historical monuments. On the subject of the fatigue of iron and steel bridges, Brandes published numerous articles in the journal Stahlbau . Brandes continued to grapple with this important subject of steel construction research after he retired.

Brandes made his extensive knowledge available as a visiting professor at the Yamaguchi University (Japan) , as a lecturer at the TU Berlin and the Potsdam University of Applied Sciences . Since 2004 he has been involved in the Institute for Applied Research in Building (IaFB) in Berlin, which was founded in 2002. On the occasion of the 15th birthday of the IaFB, he gave the lecture with Petra Kubowitz (IaFB), Werner Daum (BAM), Detlef Hofmann (BAM) and Frank Basedau (BAM) at the event Applied Research in Construction - User Conference on September 22, 2017 Long-term monitoring of bridges on the basis of adaptive structure mapping . This lecture and the two publications on the same subject are the result of the long-term monitoring of the prestressed concrete bridges at Berlin Central Station .

The scientific achievements of Brandes and his employees in the Structural Safety Laboratory at BAM for building in existing structures in general and the upgrading of outdated iron and steel bridges in particular have contributed to raising the awareness of civil engineering when dealing with historically significant bridge structures.
