this is a very cool looking dome. not my one by the way. is it as strong as a 3v 5/8 dome with the triangles. Or do you loose alot of strength with this tipe of dome? and how much strength do you thing you would loose. i thing the eden progect is simaler..
thanks all

| As a hub-&-strut frame, this dome (truncated icosahedron, buckyball, or "flattened" soccer ball) isn't nearly as strong as the 3vicosa triangulated version. However, if you use a thick skin of plywood, oriented strand board (OSB), wooden planking, or maybe sheet metal, then it will be fine for a small garden shed or other outbuilding. The Eden project is similar in the sense it has an exterior framework of hexagons and pentagons (sometimes called a honeycomb). But that exterior section is reinforced by a fairly complex interior framework of lower-gage steel pieces. Taken together, they call that framework hex-tri-hex. Gerry in Quebec | |

| It looks nice, since I like soccer, but I am not sure how strong it is compared with the 3v dome. Good luck with your project. Jorge El Salvador Central America | |

| Hi Gerry, If you look closely you`ll notice the internal steel framing much like the hex-tri-hex geometry. Hi Jeepster, Its no less sturdy than the full 3v icosa it replaced and it has much bigger windows :) | |

| Hi Jorge, Regarding strength, consider a truncated 3v 5/9 icosa (soccer ball) has 65 struts, a fully triangulated 3v icosa 5/9 has 165 struts. The dome in the picture uses 205. | |
