Wind subjects the frame to uplift forces. Overturning forces on the sides and ends of the building. Drag forces on the roof and sides. These destabilizing forces are resisted essentially by the weight of the building and in this regard, the foundations contribute significantly to this weight. The foundations are regarded as the building's anchors.
Compared to traditional or conventional buildings, tension fabric buildings may have lower operational costs due to the daylight that comes through the fabric roof when light-coloured fabrics are used. This natural lighting process is known as daylighting and can improve both energy use and life-cycle costs, as well as occupant health. [1] [2]

Proof testing involves the application of successively larger loads on the tieback with a loading jack, allowing for the recording of a load-elongation curve according to gauge readings.

They are designed as simple spans supporting equally spaced concentrated loads for a floor or roof system. These concentrated loads are considered to act at the panel points of the Joist Girders. These members have been standardized for depths from 20 to 120 inches (510 to 3,050 mm), and spans to 120 feet (37,000 mm).
