Archway Tensile Structure Solutions
Archway India stands as a premier tensile structure manufacturer, designer, fabricator, and architect, delivering innovative solutions worldwide. Tensile structures, also known as tension or membrane structures, represent a revolutionary form of lightweight architecture that relies on tensile forces rather than compression for stability.
Tensile structures use high strength fabrics or membranes prestressed to achieve rigidity, supported by masts, cables, or compression rings. These systems carry only tension, avoiding bending or compression in the membrane, which enables vast spans without internal columns. The form finding process involves anticlastic shapes curvatures in opposite directions for optimal load distribution, contrasting synclastic forms used in air supported designs.
Key fabrics include PVC coated polyester (PES) for cost-effective, UV/fire-resistant applications; PTFE coated fiberglass for superior durability and translucency; and ETFE for lightweight, self-cleaning panels. These materials offer high tensile strength (up to 8000 N/5cm), low weight (0.5-1.5 kg/m²), and properties like 10-20% translucency for natural daylighting while reflecting solar heat. Archway India employs these in engineered panels, high-frequency welded for seam integrity.
Design begins with 3D modelling for form-finding, followed by finite element analysis to simulate wind (up to 200 km/h), snow, and seismic loads per international standards like IS 875. Components include edge cables (galvanized or stainless steel), modular masts, and anchorage systems; patterning ensures precise membrane fit post-tensioning. Archway's process integrates BIM for detailing, ensuring compliance with fire ratings (Class 1) and UV resistance exceeding 20 years.
