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
