Clarification of Membrane Structures

Framed Eembrane Structure

Loading weight is supported by frame and membrane is useed as a secondary structural material or finishing materials

Suspended Membrane Structure

Bottom part is supported by membrane and the membrane is supported by prop, arch, or cable, etc

Air Supported Structure

Air Inflated Structure

PNEUMATIC

Pneumatic Stucture

Single Air-supported Membrane Structure

Supports the structure with in-flowed air pressure
(20-50mm/Aq)

Double Air-supported Membrane Structure

Supports the structure with enforced in-flowed air
(150-650mm/Aq)
