Air-supported structure

[1] The concept was implemented on a large scale by David H. Geiger with the United States pavilion at Expo '70 in Osaka, Japan in 1970.

If this is not the case, the structure will be unevenly supported, creating wrinkles and stress points in the pliable envelope which in turn may cause it to fail.

The main loads acting against the air-supported envelope are internal air pressure, wind, or weight from snow build-up.

Modern structures have computer controlled mechanical systems that monitor dynamic loads and automatically compensate the inflation for it.

Early anchoring designs incorporated sand bags, concrete blocks, bricks, or the like, typically placed around the perimeter on the seal skirt.

The danger of sudden collapse is nearly negligible, because the structure will gradually deform or sag when subject to a heavy load or force (snow or wind).

Only if these warning signs are ignored or not noticed, then the build-up of an extreme load may rupture the envelope, leading to a sudden deflation and collapse.

[5] A common misconception is that these structures are not meant to be permanent facilities, however all major corporations participating in this industry conform to some form of The International Building Codes.
