Numerical Analysis on “Kana-Ami” Structure Between Expert and Non-expert

“Kana-ami” is a kind of metal wire network in Japan, which was once prevailed many years ago in the old Japan and has been decreased in the development of social industrialization. In previous research, the characteristics of the “Kana-ami” hexagonal structure were clarified, the metal wire net of “Kana-ami” made by expert presented the convex shape in vertical direction so that helps buffer the fall. The results confirmed the superiority of the product made by expert. In this research, the actual structure of “Kana-ami” was clarified by X-Ray. And the advantage of the expert’s product was confirmed. The three-dimensional analysis method was applied to present the different actual structure.
