Describe air-supported structures.
What will be an ideal response?
Air-supported (pneumatic) structures derive their structural integrity from pressurized air used to inflate a flexible material, like structural fabric, making air the main support of the structure. To maintain structural integrity, a structure is pressurized to produce internal pressure that equals or exceeds external pressures, such as wind forces. Air-supported structures use either single or multiple wall enclosures made of a flexible membrane material. A single skin utilizes one outer layer with the air pressure exerting directly against that skin. A double skin is similar to a single skin, but with an attached liner that is separated from the outer skin and provides an airspace which serves for insulation, acoustic, aesthetic or similar purposes.
