Klaus Pieper

Klaus Pieper (born May 27, 1913 in Cologne ; † November 16, 1995 in Braunschweig ) was a German civil engineer .

life and work

Pieper was the son of the architect and later Lübeck building director Hans Pieper . After studying at the Technical University of Dresden , he received his doctorate here in 1939 with a thesis on rain runoff from street surfaces.

As his father's assistant in the security work after the air raid on Lübeck on March 29, 1942 , however, he developed into a specialist in the static security of historical buildings. In 1947 he made the first structural diagnosis of the Marienkirche , which laid the structural basis for its reconstruction.

Together with the master builder Erich Trautsch , he developed the Trautsch-Pieper process, named after both of them, for the production of light, cost-saving and non-combustible roof trusses from slag hollow blocks instead of wood, which is also used for the roof and the towers of the Marienkirche as well as the towers of the Petrikirche and the Doms came to execution. In 1953 Trautsch received a patent for this, and in 1956 both for the development of a concrete rib for inclined or curved walls, such as roof walls, vaults or the like , which were used in numerous new church buildings, including the Catholic Bonifatius Church in Lübeck designed by Emil Steffan . Beyond his appointment to Braunschweig, Pieper accompanied the reconstruction of five of Lübeck's seven towers statically and constructively.

From 1947 to 1959, Klaus Pieper was the chairman of the (regional) concrete working group at the Arbeitsgemeinschaft für contemporary Bauen eV in Kiel .

In 1959 Pieper was appointed professor for structural engineering at the Technical University of Braunschweig . At his chair, the building standard DIN 1055 Part 6 for silo structures was developed with the help of a silo test field . Since 1961 he has had his own engineering office in Braunschweig, from 1971 in partnership with his former assistant Peter Martens. The numerous public construction projects supervised by the office include the Braunschweig city hall , the research reactor of the Physikalisch-Technische Bundesanstalt (PTB) and the research center of the Max Planck Society in Göttingen . But the static securing and restoration of listed buildings, especially churches in and around Braunschweig, remained a main field of work until he retired for health reasons in 1978.

Since 1971 he has been a member of the Braunschweig Scientific Society .

Fritz Wenzel and Peter Martens are among his doctoral students .
