Inflatable membrane structure introduction
The inflatable membrane structure utilizes a membrane-belt anchoring system to ensure stability and functionality under external and internal forces.
The inflatable tubes are the most important structural element of the structure. They consist of a lightweight membrane filled with air via a blower system. The (low) internal pressure in the tubes ensures the required rigidity of the structure while maintaining a very low weight.
This pressure is regulated by an automatic control system that increases the stiffness of the tubes at peak wind speeds depending on the current wind strength.
The stability of the tubes is ensured by an innovative belt mesh, designed as a cage-like structure around the inflatable membrane. It fulfills two main functions: limiting the deformation of the tubes and transferring the internal forces to the anchoring points.
The belt mesh is interconnected to form a network, so that the forces acting on the membrane are transferred in the form of axial forces via the belt mesh to the anchoring points.
A key advantage of air-supported structures is their ability to create expansive, column-free spaces ideal for events or storage. The constant air pressure ensures stability, while advanced materials provide insulation and UV resistance. Though requiring continuous airflow, modern systems optimize energy use. Their versatility, eco-friendliness, and low maintenance make them popular for both temporary and semi-permanent applications in architecture and engineering.
