biography

Katzenbach studied civil engineering at the TH Darmstadt from 1969 , where he graduated in 1975 (in structural engineering), then worked as a research assistant at the Institute for Geotechnics under Herbert Breth , where he received his doctorate with honors in 1981 ( development tendencies in construction and computation closer to the surface Tunnel in built-up urban area ). He then worked as a manager in engineering offices (from 1989 as a publicly recognized expert for earthworks and foundation engineering) before becoming professor at the TU Darmstadt and director of the institute and the research institute for geotechnics in 1993. In 1995/96 he was dean of the civil engineering department. Since 2007 he has also been director of the Energy Center at TU Darmstadt. In addition, he has had his own engineering office, Professor Dr.-Ing. Katzenbach .

Katzenbach was in the 1970s in the investigation of high-rise building foundations (and high-rise settlements) and deep excavations in Frankfurt (the Frankfurt tone that there is a thickness of about 40 to about 100 has m) and their numerical modeling using finite elements involved (Herbert Breth and Peter Amann were the leaders in development in Darmstadt in the 1970s ). Specifically from the experience in Frankfurt, Katzenbach and others developed a combined pile raft foundation (KPP, English CPRF) in Darmstadt, which was used in various Frankfurt high-rise projects (such as the Main Tower and Messeturm ). Katzenbach and others used the procedures for the KPP to analyze, for example, the load-bearing capacity of the Berlin Reichstag, which was built on wooden stakes . and he advised in Berlin, among other things at the Sony Center. He had further building ground consultations in addition to Frankfurt and Berlin in Moscow (e.g. Federation Tower ), Kiev , Shanghai and in Darmstadt, for example at GSI .

Katzenbach was also responsible for the founding concept of the tallest German skyscraper, the 300 m high Commerzbank Tower in Frankfurt (built 1994 to 1997). Because of other neighboring high-rise buildings, the settlement had to be minimized, which is why it was not founded with KPP, but with piles that were inserted into the limestone beneath the Frankfurt clay. The decisive factor for the feasibility was the skin friction to be applied in the limestone, whereby Katzenbach and colleagues were able to increase the conservatively low value previously used for this in Frankfurt building projects by a factor of ten (to 400 kN per square meter) through tests and numerical modeling.

In addition to the interaction between the structure and structure of high-rise buildings, deep construction pits and tunnel construction (including the Frankfurt subway), he also focuses on energy foundations ( energy piles , geothermal energy use , seasonal thermal storage).

He was chairman of the technical committees of ISSMGE TC 5 (Environmental Geotechnics) and has been chairman of TC 18 (Deep Foundations) since 2003. He is on the board of the DGGT . He is co-editor of the journal Der Bauingenieur . In 2013 he gave the Vienna Terzaghi Lecture .

  5. ↑ There the stiffness of the clay increases with depth, which makes it advantageous to transfer the loads via piles to greater depths in the clay. Previously, the high-rise buildings there had often been built flat on foundation slabs with readjustments during the settlement phase. At the 162 m high Marriott Hotel (built 1973 to 1976), a settlement of 34 cm had to be compensated for by constructive measures.
  6. ↑ It was used in Frankfurt from the 1980s. There was already a parallel development in the 1970s for high-rise building in the London tone.
