Study Notes
Thermoplastic Membranes
- Comprised of polymeric materials that can be re-shaped when heated.
- Common types include PVC (Polyvinyl Chloride) and PTFE (Polytetrafluoroethylene).
Tensile Structures Loading
- Loaded in tension, distributing forces along the fabric.
- Each part is subjected to tensile stress rather than compressive or bending loads.
Tension in Pneumatics
- Created by the internal pressure within the inflatable structure.
- Pressure generates a buoyant force, maintaining the shape and stability.
Uncoated Fabrics
- Typically made of woven materials like polyester or nylon.
- Lacks additional protective layers, offering higher breathability and lower weight.
Cable Nets Purpose
- Serve as a supporting framework in membrane structures.
- Distribute loads and provide structural integrity through tension.
Thermoplastic vs. Thermoset Systems
- Thermoplastic membranes can be re-formed and recycled; thermosets cure permanently upon heating.
- Thermosets generally have better chemical resistance but lack flexibility of thermoplastics.
Distinction of ETFE
- ETFE (Ethylene Tetrafluoroethylene) is highly transparent and UV resistant.
- Lightweight and has excellent durability compared to other plastic films.
Defining Characteristic of Tensile Structures
- Characterized by their ability to efficiently transmit and balance loads through tension.
- Utilize flexible materials that can deform under load without failure.
Role of Cable Nets in Membrane Structures
- Provide additional stabilization and load distribution.
- Act as a grid to support various tensioned membrane forms.
Synclastic Surfaces in Membranes
- Defined by surfaces that curve in the same direction in both principal curvatures.
- Result in a double curvature which enhances structural efficiency and aesthetic appeal.
