Protoscape Architecture: Hiroshi Naito’s Earthquake-Resistant Kusanagi Sports Complex
Hiroshi Naito, a renowned architectural theorist, is dedicated to creating modern, enduring architecture that can last for over a century. His latest project, the Kusanagi Sports Complex Gymnasium, is Japan’s largest wooden structure, and it recently opened in Shizuoka Prefecture. In the post-3.11 era, Naito emphasizes the importance of shifting from “protoform” (an individual’s dream living) to “protoscape” (a shared dream landscape for a collective group of people).
In Japan, designing buildings with durability and earthquake resistance is of utmost importance. To support the massive roof of the Kusanagi Sports Complex Gymnasium, which has a load of 2,350 tons, Naito implemented an innovative design. He used 256 cedar-bonded blocks of wood, each measuring 14.5 meters in length, as pillars arranged elliptically while varying angles between 45 and 70 degrees. Steel braces on the back of the bonded wood provide support for short-term loads.
To counteract the thrust force at the base of the bonded wood, which tends to extend outward, post-tension is applied to the lower part of the bonded wood by installing RD horizontal rings. This design ensures stability and strength, allowing the gymnasium to serve as a safe and durable architectural masterpiece for the community to enjoy for generations to come.
