IASS Hangai Prize

The Hangai Prize MedalIn 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, and engineers 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, e-mail the prize committee.

18th Hangai Prize, 2020: The next round of the Hangai Prize competition is for the IASS 2020 Symposium to be held at the University of Surrey, Guildford, UK, 24-28 August 2020. General application instructions, as they become available, are detailed below, including the specific deadlines.  Please note that the deadline for the full paper submission to the Hangai Prize Committee is likely to be earlier than the deadline for submission of full papers to the IASS 2020 Symposium.


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 together with the completed Hangai Prize entry form to the designated Hangai website by the established deadline (and also upload the full paper to the symposium website by the specified date), and
  5. if selected as a winner, attend the Symposium to present the paper in a plenary session and to receive the prize.

Presentation and Benefits

The Prizes are presented during the Annual Symposium.  Each prize consists of:

    (1) a certificate and medal,
    (2) reduced fees for the symposium,
    (3) a free one-year IASS Awardee membership for the full calendar year following the symposium, and
    (4) publication of the contributions in both the Symposium Proceedings and the Journal of the IASS.

As an incentive for entering the competition, all applicants - whether winners or not - who attend and present their papers at the Annual Symposium receive a free one-year IASS Awardee membership for the full calendar year following the symposium.
