At the 2021 Annual Symposium, the Tsuboi Award for the best paper in the Journal of the IASS in 2020 was conferred to:

Ch. Robeller and N. von Haaren (Germany): "Recycleshell: Wood-only Shell Structures Made From Cross-Laminated Timber (CLT) Production Waste," J. IASS, Vol. 61 (2020) No. 2, n. 204 June, pp. 125-138.

There was only one award for 2020, because the Symposium award was not conferred since the 2020 symposium was postponed until 2021 due to the Covid-19 pandemic.

The Hangai Prize Committee announced the winners of the 19th Hangai Prize, and their papers were presented at the 2021 Annual Symposium:

• Ting-Uei Lee (Australia): "From ruled surfaces to elastica-ruled surfaces: New possibilities for creating architectural forms"

• Kotaro Sempuku (Japan): "Self-folding rigid origami based on auxetic kirigami"
  
• Xiuming Liu (China): "Study on thermal damage of large-span ice shell structure based on thermal-mechanical coupling"
• Qian Zhang (China): "Programmable and reconfigurable surfaces with kirigami-inspired bistable elements"

The papers will be included in the December 2021 issue of the Journal of the IASS.

Congratulations to all the winners!
