Jørgen Brinch Hansen (around 1960)

Jørgen Brinch Hansen (born July 29, 1909 in Aarhus , † May 27, 1969 in Copenhagen ) was a Danish civil engineer specializing in foundation engineering and soil mechanics.

Life

Brinch Hansen graduated from Denmark's Technical University in Copenhagen with a degree in civil engineering in 1935 . He then worked for 20 years in the design office of the Copenhagen construction company and engineering firm Christiani und Nielsen, mainly in port and bank construction. He became chief engineer there, but also began to deal scientifically with soil mechanics and published in the first issues of Geotechnique in 1949/50. In 1953 he was in Copenhagen with an extensive study of earth pressure problems, for which he developed his own load bearing method ( Limit Design) developed a doctorate. The main motivation for him were earth pressure calculations for anchored bank sheet pile walls. He developed simplified calculation formulas and partial safety concepts based on his application of plasticity theory for a wide variety of basic structural problems. In 1955 he became professor of soil mechanics and foundation engineering at the Technical University of Denmark in Copenhagen and at the same time director of the Danish geotechnical institute. He was Chairman of the Danish Geotechnical Society and Vice President of the International Society of Soil Mechanics for Europe. He was on the German working committee for bank edging and since 1961 chairman of the committee for Danish foundation engineering guidelines, in the version of which from 1965 his own theories were incorporated. In particular, the concept of partial safety factors, which Brinch Hansen pursued as early as the 1950s, later established itself in the Eurocodes and in many European national guidelines.

As an engineer, he was involved in the bridge projects over the Great and Little Belt and in tunnel projects in Copenhagen.

He was a member of the Danish Academy of Science and Engineering and was awarded an honorary doctorate from Ghent University in 1965 .

It opened a branch in Hamburg in 1909 and continued to expand internationally after the First World War .

  2. ↑ Partial safety factors were introduced by Donald Wood Taylor in 1948 (for the angle of friction and cohesion in earth pressure problems). Brinch Hansen extended this considerably to include loads, for example. See also Geoffrey Meyerhof Evolution of Safety Factors and Geotechnical Limit State Design , 2nd Spencer J.
