Biography



Early life

Yasuhiko Hangai was born on 25 April in 1942 as the second of five children, all sons, of Katsumi (father) and Ai (mother) Hangai. His father Katsumi served as a junior-high school teacher in

Asaka High School in Fukushima
.



Career

He began a private practice in Germany in 1952. His saddle-shaped cable-net music pavilion at the Bundesgartenschau (Federal Garden Exposition) in Kassel brought him his first significant attention. He earned a doctorate in tensioned constructions in 1954.[1]

Otto specialised in lightweight

Arena. He has lectured worldwide and taught at the Architectural Association School of Architecture, where he also designed some of the research facilities buildings of the school's forest campus in Hooke Park.[2]

Until his death, Otto remained active as an architect and engineer, and as consultant to his protégé Mahmoud Bodo Rasch for a number of projects in the Middle East. One of his more recent projects was his work with Shigeru Ban on the Japanese Pavilion at Expo 2000 with a roof structure made entirely of paper, and together with SL Rasch GmbH Special and Lightweight Structures he designed a convertible roof for the Venezuelan Pavilion.[2] In an effort to memorialise the September 11 attacks and its victims as early as 2002, Otto envisioned the two footprints of the World Trade Center buildings covered with water and surrounded by trees; his plan includes a world map embedded in the park with countries at war marked with lights and a continuously updated board announcing the number of people killed in war from 11 September 2001, onward.[3]

On request of de:Christoph Ingenhoven, Otto designed the "Light eyes" for Stuttgart 21.[4] – drop-shaped overlights in the park, that descend onto the tracks to support the ceiling.[5][6] Otto remarked in 2010 that the construction should be stopped because of the difficult geology.[7][8]

Otto died on 9 March 2015; he was to be publicly announced as the winner of the 2015

Pritzker Prize on 23 March but his death meant the committee announced his award on 10 March.[9][10] Otto himself had been told earlier that he had won the prize by the executive director of the Pritzker Prize, Martha Thorne. He was reported to have said, "I’ve never done anything to gain this prize. Prize winning is not the goal of my life. I try to help poor people, but what shall I say here — I'm very happy."[10]


Career

After graduation from the high school then he entered the University of Tokyo (Natural Science I). He majored in Architecture and joined the Umemura lab at Hongo campus for his graduation thesis and the Tsuboi lab at Institute of Industrial Science for the graduate course.

As part of his master thesis, Hangai helped with numerical calculations of a double-layer space frame roof constructed at Uchinoura Space Center to house epsilon rockets [11]. He continued his doctoral studies in the same lab and in the second year,1969, he was offered to be a research associate when Professor Yoshikatsu Tsuboi retired, and the lab was taken over by Shigeya Kawamata as the associate professor. In the same year, Hangai married Naoko Kojima, who was a research officer of chemistry in the same institute. He obtained a doctorate degree of engineering from the University of Tokyo with his thesis “Analysis of Geometrically Nonlinear and Stability Problems by Static Perturbation Method” on 22 March 1973.

In 1975, when Professor Kawamata moved to the

IASS
*1.


Lifestyle and passing

Hangai arrived at the lab at 8:30 am every morning, finished lunch in 15 minutes, and intensively enjoyed playing “Go” or “Shogi” (Japanese chess) with colleagues in neighboring labs. In the evening, he finished his work at 5:15 pm and never worked overtime. After work, he enjoyed playing Go, Shogi or chatting with friends or students. Hangai had a variety of hobbies, such as mountain climbing, playing Go and Shogi, skiing, playing tennis,

. Hangai was consistently encouraging to young researchers. Many of his colleagues, including many younger researchers, admired him for his cheer and generosity. On 5 August in 1998, during an annual summer seminar held at Iizuna, Nagano, he suddenly broke down. Four days later, he passed away on 9 August. Among his classmates in the Department of Architecture of the University of Tokyo, Toyoo Ito (architect), Shin’ichi Sugawara (Professor Emeritus, University of Tokyo), Yoshio Tsukio (Professor Emeritus, University of Tokyo), Takao Nishikawa (Professor Emeritus, Tokyo Metropoitan University) and Shuzo Murakami (Professor Emeritus, University of Tokyo). In Hangai’s obituary, Toyoo Ito wrote, “Mr. Hangai in my memory is always smiling. I do not know other anyone who had filled one’s life with such cheerful smiles... If I had not changed my mind in registering for the (Tsuboi) laboratory, I would have been next to him in the lab.” [12].

Works

Hangai’s works specialized in non-linear behavior and its numerical analysis of thin curved structures, such as shells, space frames and membrane structures. These are often classified as “spatial structures”. He was a leading pioneer in instability problems of thin shells and space frames in Japan. He also initiated the applications of generalized inverse to structural analysis with Professor Hisashi Tanaka, which was very early even at a global level. Afterwards, he was one of the researchers who started so-called “computational morphogenesis”, which eventually became a big new trend in the field of structural and architectural design. In addition to serving as a professor at the University of Tokyo (Institute of Industrial Science), Hangai also played a very important role in and made essential contributions to establish the Japan Society of Computational Engineering and Science (JSCES) with Professor Tadahiko Kawai. In a research group of computational engineering and science, the predecessor association of JSCES, he led the special research group for non-linear problems, in which he mentored and fostered many young researchers.

In 1984, Hangai started Japan-Korea summer colloquium on shell and spatial structures with prof. Teak-jin Kwun, which has gradually grown as Asian Pacific Conference on Shell and Spatial Structures, which involves other Asian countries, Australia and west coast of USA.


Hangai Prize

1972 Munich Olympic Stadium

After sudden death of Yasuhiko Hangai, his widow, Mrs. Naoko Hangai, placed a donation under care of a group of his former students to be used for the development of research of spatial structures. They used the donation to establish a prize for young talented people, “Hangai Prize”, in the IASS based. It has been awarded to four young researchers, engineers or architects every year since 2003. The medal given to the awardee was designed by Professor Katsumi Nagase (Hosei University) and Mrs. Hangai.
