Awards given over the years from the International Association for Shell and Spatial Structures (IASS) and the International Conference on Spatial Structures.

Pioneers’ Award

It has been a tradition of the Spatial Structures Research Centre of the University of Surrey, to recognise and honour those who have made significant contributions in the field of spatial structures. This is done through a special award called the "Pioneers' Award", given during the International Conferences on Spatial Structures.

The Centre is going to carry on with the tradition and the new recipients will be announced during the conference in 2020/21.

Tsuboi Award

The Tsuboi Award was established in 1991 with the help of a donation from the late Mrs. Kazuko Tsuboi. This award honours the memory of Professor Yoshikatsu Tsuboi (Japan, 1907-1990), former President and Honorary Member of the IASS, and his outstanding contributions to structural and architectural design.

Tsuboi Awards are awarded annually by the Tsuboi Awards Committee in two categories:

  1. For the most meritorious paper published in the journal of the IASS in the preceding calendar year
  2. For the most outstanding paper presented and published in the proceedings of the previous year's annual IASS Symposium.

Hangai Prize

Hangai Prizes annually recognize talented young researchers, designers, and engineers working in the field of shell and/or spatial structures. This recognition is achieved by selecting outstanding submissions to the Annual IASS Symposium in the form of research papers, resumes of design projects, or presentations of innovative ideas.


Submissions for the Hangai Prize 2020 have now closed. The winning papers will be published in the December 2020 issue of the IASS Journal. Applications for the Hangai Prize 2021 are yet to be announced, please check back again soon for further updates.

Both the 2020 and 2021 awards and presentations will take place at the Spatial Structures Conference in Guildford, August 2021.
