Which node connection form is generally used for membrane structures?

Membrane structures typically utilize several types of node connections:

Cable Node Connections: Cable nodes are common connections in membrane structures. In cable nodes, membrane materials are usually connected to support structures or other membrane materials through cable structures. This connection form can achieve large spans in membrane structures while providing good translucency and aesthetics.

Welding or Heat Sealing Between Membrane Materials: For certain membrane structures, such as polymer films or polyvinyl chloride (PVC) membrane structures, welding or heat sealing can be used to connect seams between membrane materials. This connection method ensures the sealing and strength of the seams, resulting in good airtightness and waterproofing for the entire membrane structure.

Nodal Connections: Nodal connections are also common in some complex membrane structures. This connection form typically uses specialized nodal components to connect membrane materials to support structures, ensuring overall stability and structural performance. Nodal connections can enhance the wind resistance and seismic performance of membrane structures.

Clamp Connections: Clamp connections involve pre-tensioning membrane materials and fixing them onto support structures. This connection form ensures the flatness and surface quality of membrane structures while improving their load-bearing capacity and stability.

In summary, the node connection forms in membrane structures depend on specific design requirements, material characteristics, and environmental conditions. Different types of membrane structures may utilize different connection methods to achieve stability, load-bearing capacity, and aesthetics.
