At the Awards Conferral Ceremony of the 2024 Annual Symposium, the 22nd Hangai Prizes were conferred to the following winners, who all later presented their papers at the symposium:

• Elena SHILOVA (UK): “A Framework for Parametric Structural Design of Topological Interlocking Flat Vaults”
• Guusje UBACHS (UK): "Walking on eggshells: innovative methods to justify reuse of a historic thin shell roof at Smithfield Poultry Marke"
• Hiroki AWAJI (Japan): “Verification of Flexible Cable-net Formwork Method for GFRC Panel Manufacturing Using Structural and Physical Optimization”
• Seri NISHIMOTO (Japan): “Transformable Surface Mechanisms based on Bending-active Scissors Structures”

Their papers will not only appear in the Proceedings of the 2024 Symposium but will also be published in the December 2024 issue of the Journal of the IASS.

In addition to their medals and other benefits, each of the winners will receive one dues-free year of IASS membership. (This award of one-year dues-free membership accrues also to each of the non-winning entrants into the Hangai Prize competition who presented their papers at the 2024 Annual Symposium.)
