Form finding in elastic gridshells

Pedro Miguel Nunes Pereira de Almeida Reis, Changyeob Baek

Elastic gridshells comprise an initially planar network of elastic rods that are actuated into a shell-like structure by loading their extremities. The resulting actuated form derives from the elastic buckling of the rods subjected to inextensibility. We s ...
