German Committee for Reinforced Concrete
The German Committee for Reinforced Concrete eV (DAfStb) is a specialist body to promote concrete construction . It existed from 1907 until 1941 under the name of the German Committee for Reinforced Concrete . It has the legal form of a registered association with its seat in Berlin .
The DAfStB deals with research and publishes series of documents (booklets) as a special feature which, in addition to the relevant standards, contain guidelines for concrete construction that are part of the recognized rules of architecture. They are published by Beuth-Verlag (issue no.622 appeared in 2016).
history
The German Committee for Reinforced Concrete was founded in 1907. The seat was initially in the hydraulic engineering department of the Prussian Ministry for Public Works in Berlin (Leipziger Str.). In 1916, regulations for the execution of structures made of concrete and reinforced concrete were issued for the first time , together with examples. In 1917 DIN was founded as a German standards committee. Work on concrete and reinforced concrete was put out to tender and purchased, and committees for concrete in bog and seawater were established. In 1925 there was an expanded new edition of the provisions that were also adopted by the DIN committee (DIN 1044 to 1048). In the third edition in 1932, experts were able to comment for the first time, which led to 1500 submissions, some of which were very detailed. In 1941, by decree of the Reich Ministry of Transport, the committee was renamed “German Committee for Reinforced Concrete”. In the hundredth issue of 1944 an overview of the previous activities was given. Most of the committee's documents were lost during World War II (they had been relocated to Potsdam) and the committee temporarily ceased its activities in 1945. The secretary of the committee (Amtsrat Ritter, since 1933) was killed in a bomb attack in the office in 1944. When the German Standards Committee (DIN) resumed its work in 1946, the DAfStb, which had already worked with it, could begin work again. When Berlin was founded, the seat was determined (for historical and political reasons) to be the magistrate or senate administration for building and housing (from 1950 in the Berlin office of the Federal Ministry for Housing in Bundesallee). He was incorporated into the building industry's technical standards committee founded in 1947. In 1949 the committee resumed its work and first published DIN 4231 on the repair of damaged reinforced concrete structures.
In 1953 the first prestressed concrete standard (DIN 4227) was published. The reinforced concrete regulations were also fundamentally revised and the draft of DIN 1045 was presented in 1968. 2500 comments were received on the draft. In 1972 the new version of DIN 1045 was issued (and related standards). In the 1970s, cooperation with European standards committees (preparation of the Eurocode ) began. From 1974 the committee held regular research colloquia at different universities. New editions of the central DIN 1045 appeared in 1978 and 1988. The 2001 version is already based on the Eurocodes.
In 1991 the seat of the committee with the Federal Ministry moved to the former eastern part of the city on Scharrenstrasse. In 2001 the office was incorporated into DIN (based on Burggrafenstrasse in Berlin-Tiergarten).
The DAfStb represents Germany in the Fédération internationale du béton (fib).
