Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.
The authors are extensively involved in planning, operating and inspecting, designing and testing as well as updating specific rules as well as R&D. Univ.-Prof. Dr.-Ing. Stephan Freudenstein has been a full professor at the Chair and Institute of Road, Railway and Airfield Construction at Technical University of Munich and director of the test institute of the same name in Pasing, Munich, since 2008. After studying civil engineering at TUM (1995) and working at Heilit + Woerner Bau AG, Stephan Freudenstein became a research associate at TU Munich`s Chair and Institute of Road, Railway and Airfield Construction in 1997. In 2002, he joined Pfleiderer Infrastrukturtechnik GmbH, now known as RAILONE GmbH, in Neumarkt in der Oberpfalz/Germany. While there, he headed up the technology and development department. He was responsible for prestressed concrete sleepers and the technical side of various ballastless track projects in Germany and farther afield. The main focus of Prof. Freudenstein`s research is the structural design of road and rail superstructure systems and aviation surfaces. He is a member of numerous German and European technical standard committees and committees of independent experts. Dr.-Ing. Konstantin Geisler studied civil engineering at TU Munich (2010). In 2016 he got his doctorate there and works in academic research at TU Munich`s Chair and Institute of Road, Railway and Airfield Construction. Dipl.-Ing. Tristan Molter studied civil engineering at TU Munich. Since 2000 he is responsible for noise protection, bridge equipment and provisional bridges at the technology and plant management dept. of the Deutsche Bahn DB Netz AG at Munich. He is the chair of the structural engineering commission (FA KIB) at VDEI (association of the German railway engineers) and a member of numerous German and European technical standard committees and committees of independent experts. Dipl.-Ing. Michael Mi?ler studied civil engineering at TU Munich. Since 2000 he is responsible for ballastless track technique in the track technology management dept. of Deutsche Bahn DB Netz AG in Frankfurt on the Main, Germany. He is a member of numerous German and European technical standard committees and committees of independent experts. Dipl.-Ing. Christian Stolz studied civil engineering at TU Munich. Since 2000 he is he is responsible for ballastless track technique in the track technology management dept. of Deutsche Bahn DB Netz AG in Frankfurt on the Main, Germany. He is a member of numerous German and European technical standard committees and committees of independent experts.
