Fourth year Engineering student Cam Millar has been announced the winner of the Institution of Structural Engineers’ Guthrie Brown Award for his paper titled 'Design of the world’s first sprayed-net, hyperboloid, lattice ice structure'.
The Harbin project was fascinating and a great showcase of Cambridge engineering and architecture talent. It is an honour to win this award and it is a credit to the whole team for their amazing work.Student Cam Millar
The paper provided details of the design and construction of the world’s first hyperboloid cable net ice structure – a structure that won Cam and his team the Best Design and Construction Works Award at the 2018 Harbin Institute of Technology’s annual International Ice and Snow Innovation Construction Competition.
Over a seven-day period, a team of 11 students from the Department of Engineering and the Department of Architecture designed and built the ice structure on a 10m x 10m plot in temperatures as low as -20°C. They created a hyperboloid cable net ice structure that was strong in compression and weak in tension. Using a rope suspended from a crane, the structure was sprayed with ice to create a rigid hyperboloid.
Cam said: "The Harbin project was fascinating and a great showcase of Cambridge engineering and architecture talent. It is an honour to win this award and it is a credit to the whole team for their amazing work. It feels amazing to continue the Cambridge traditions of pushing boundaries with novel and exciting projects. Working in such a skilled team and on such an expressive project has definitely inspired me to work on more boundary-pushing structural projects."
