Ryo Tanabashi

Ryo Tanabashi (born March 2, 1907 in Shizuoka , † May 5, 1974 in Kyoto ) was a Japanese civil engineer.

Tanabashi went to school in Nagoya and studied from 1926 to 1929 at the University of Kyoto . From 1929 to 1931 he was a lecturer at the Technical University in Kobe, then was an assistant professor at the University of Kyoto, where he received his doctorate in 1936. In 1945 he received a full professorship and in 1951 he became the founding director of the Research Institute for the Prevention of Natural Disasters. In 1970 he retired and taught at Kinki University in Osaka .

In 1937, he developed what was then a revolutionary method for dimensioning buildings for earthquakes, including energy absorption and plastic limit cases based on the load-bearing theory. The criterion was verified in 1956 by George W. Housner in the Alaska earthquake at an oil refinery.
