This giant umbrella of a pavilion is made by stretching oversized sheets of curved plywood, each as much as 8 feet wide and 36 feet long, over the steps of the architecture department at the Swiss Federal Institute of Technology (ETH).
A plywood structure that big and heavy should collapse on itself. But by carving perforations into the wood, the designers made it easier to bend and more resistant to powerful wind loads. Then, they arranged the plywood sheets to overlap and interlock, creating a set of “self-stabilizing vaults.” Cross-bracing cables help keep everything in place.
The pavilion was a collaboration between the Chair of Structural Design at ETH and the Emergent Technologies and Design program at the Architectural Association (AA) in London. Read more about it at ArchDaily.com.
