The design of tensile fabric structures establishes the form, span and fixing points for each project. Steel or aluminium frames can support a tensioned membrane, using posts, masts or perimeter beams. Resolve site access, wind exposure, drainage and the required clear height before fabrication.

Tensile structure planning

Tensile structure fabric material must match the structure’s exposure and intended use. The specification can include coated polyester or PVC-coated fabric, with seams, edge cables, plates and connection hardware. Assess the fabric weight, coating, fire performance, UV resistance and cleaning requirements against the project brief.

The types of tensile fabric structures for building and event applications include freestanding canopies, entry covers and linked shade forms. A canopy tensile structure requires suitable footings and water management, while a cable tensile structure depends on correctly positioned anchors and tensioned cables to hold the membrane in its designed plane.

What should be checked in the design of tensile fabric structures?

Confirm the site dimensions, wind conditions, drainage path, clearances and footing locations. The engineer should coordinate fabric geometry with lighting, services and access requirements.

What is tensile structure fabric material made from?

PVC-coated polyester and PTFE-coated glass fibre are common options, selected for span, exposure and fire requirements. Record the coating, colour, weight, warranty conditions and cleaning method in the project specification.

How does a cable tensile structure work?

Cables transfer tension between the membrane, supports and anchors. Accurate setting-out and engineered connections ensure the structure holds its intended shape under wind and rain.
