Types of membrane structures and membrane performance
Membrane Structure
- Framed membrane Structure
- The frame bears the load and the membrane is used
as a secondary structural material
or finishing material.
- Suspension Membrane Structure
- The membrane bears the load
and it is supported by pillars, arches, and cables.
- Pneumatic Structure
- Single layer pneumatic structure
Secured through tensile force
by applying internal air pressure (20-50 mm/Aa)
blasted into an indoor space
Double layer pneumatic structure
Secured through tensile and bending force
by applying internal internal pressure (150-650 mm/Aa)
blasted into a double membrane
Air Supported Structure
Air inflated Structure
