Hiroshi Nakai (engineer)

from Wikipedia, the free encyclopedia

Hiroshi Nakai (Japanese 中 井 博 Nakai Hiroshi ) (born December 14, 1935 in Ibaraki Prefecture , † January 26, 2009 in Osaka ) was a Japanese civil engineer and university professor .

Life

After graduating from high school, Nakai studied civil engineering at Osaka City University , which he graduated with a Bachelor of Science degree in 1959. He was followed by a Master of Science degree at the same university in 1961. From 1961 to 1973 Nakai worked as a research assistant in the Faculty of Civil Engineering at Osaka City University. There he received his doctorate in engineering with the dissertation Study on mechanical behavior of curved girder bridges - an area in which Nakai was supposed to advance his research and which he summarized in his monograph published with Chai H. Yoo in 1988. In 1973 Nakai was appointed Full Professor of Bridge Construction by Osaka City University. After his retirement in 1999, he continued his teaching and research activities at the Fukui University of Technology as professor of construction until 2007.

In the early 1980s, Nakai began working with the Berlin steel construction professor Joachim Lindner and published his first essays in the journal Stahlbau, which was then headed by Lindner . Nakai's research spanned wide areas of steel bridge construction, such as curved steel bridges, steel columns, beam bridges made of composite steel, concrete-filled steel piers, prestressed bridge slabs, and local and global buckling of steel piers. His research results went z. B. in design rules for girder bridges with prestressed composite slabs; They also significantly influenced the rules on curved girder bridges of the American Association of State Highway and Transportation Officials (AASHTO).

Nakai has published 35 specialist books as author or co-author and more than 350 articles in well-known journals. With Akimitsu Kurita, at the suggestion of Gert Albrecht and Karl-Eugen Kurrer , he edited the May 2003 issue of the journal Stahlbau, which was dedicated to steel bridge construction. Nakai also played a key role in establishing the Japanese-German Bridge Symposium founded in 1994. In addition, in 1990 Nakai founded the biannual Japanese-Korean Symposium on Steel Bridge Construction.

Nakai was an active member of the Japanese Society of Civil Engineers (JSCE), the Japanese Society of Steel Construction (JSSC), the Japanese Society of Materials Science (JSMS), the American Society of Civil Engineers (ASCE), and the International Association for Bridge and Structural Engineering (IABSE).

The JSCE Award 1967 and the Tanaka Prize 1985 are among the honors.
