Hangai Prize

In memory of Professor Yasuhiko Hangai (Japan, 1942-1998), a very active member of the IASS and its Executive Council, and in accordance with his career-long encouragement for young people, the Hangai Prize recognizes talented young researchers, designers, engineers and architects working in the field of shell and spatial structures.  This recognition is achieved by selecting outstanding submissions to the Annual IASS Symposium in the form of research papers, résumés of design projects, or innovative ideas. 

 To address inquiries about the Hangai Prize not answered by the following sections of this page, please send an e-mail to the prize committee (hangaiprize@iass-structures.org). 


To be considered, papers must not only be submitted to the annual symposium but also be explicitly entered into the Hangai Prize Contest.  Papers that have previously been submitted for publication in the Journal of the IASS are not eligible for entry in the Hangai Prize competition.

To be eligible for the prize, the applicant need not be a member of the IASS but must:

  1. be under the age of thirty at the end of the calendar year of the Annual Symposium,
  2. be the primary contributor of the research, the project, or the idea presented and as such, be the first or sole author of the abstract and the paper,
  3. follow the procedures established by the Annual Symposium for the submission of a contribution, including the submission of an abstract by the specified date,
  4. upload a full-paper manuscript and the completed Hangai Prize entry form to the symposium upload website by the established deadline, and 
  5. if selected as a winner, attend the Symposium to present the paper in a plenary session and to receive the prize.
