DEF

A structure held up by a slight excess of internal air pressure above the air pressure in the atmosphere outside.

DEF

A structure in which gas or air pressure differentials control and ensure stability of form.

CONT

... in Pneumatic Architecture structural stability is the product of the release of internal environmental energy(air or gas pressure) within a membrane or bag(generally made of PVC coated nylon). Pneumatic Architecture is therefore a sub-category of pressurized construction(water or other liquids can also be used to pressurize). Three main types of Pneumatic structures are identified :air-inflated, air-supported, and air-controlled.

OBS

Pneumatics can be sub-divided into the two main categories of air-stabilised structures and air-controlled structures... Air-stabilised construction can be further sub-divided into two distinct classes of structure : single wall air-supported and dual wall air-inflated structures...

CONT

L'expression structure gonflable s'applique à toute structure déformable, dont la rigidité dépend uniquement de la pression intérieure. Celle-ci crée dans la structure souple une pré-tension suffisante pour que, sous les efforts extérieurs, toutes les parties de la structure restent en tension. Un grand nombre d'objets répondent à cette définition, tels que les pneus, bateaux pneumatiques, ballons, structures à ossature gonflable, à double paroi, et à simple paroi.
