Inflatable membrane structure is a kind of structure or component that uses high-performance membrane material as the "shell" of the building, through the air pressure difference between the inside and outside of the membrane to produce tension on the membrane surface, so as to form a certain stable shape and bearing capacity. The inflatable membrane structure shall have a closed inflatable space, and shall be equipped with an inflatable device to maintain the internal pressure, so as to ensure the rigidity of the membrane structure system and maintain the designed shape. Common inflatable membrane structures are: air supported membrane structure, air rib membrane structure and air pillow membrane structure.

Air supported membrane structure building is composed of main membrane material (outer membrane, inner membrane), air supply system, intelligent control system, access control system (personnel access door, emergency door, logistics door), lighting system, thermal insulation system, air conditioning system, cable net system and foundation anchoring system.
