Un immeuble à ossature bois apparente sans aucune pièces métalliques d’assemblage. Shigeru Ban toujours aussi époustouflant !
Shigeru Ban’s timber-skeleton Tamedia building left engineers « incredulous »
The system was informed both by traditional Swiss craftsmanship and the elaborate joints of Japanese miyadaiku carpentry – used to construct some of the world’s longest-surviving wooden structures such as Horyuji Temple in Nara, which is over a thousand years old.
To ensure the stability of the joints at such a large scale without the need for metal fastenings, Blumer milled the spacer beams into an oval rather than a traditional round shape to prevent them from rotating.
In addition, the building’s structural frame is made entirely from slow-grown glued-laminated spruce sourced from at least 1,000 metres above sea level in the Steiermark region of neighbouring Austria.
“These conditions give the timber better properties than trees with a faster growth rate, including improved dimensional stability,” reported Swedish wood magazine Trä.
