|Compression structure||Tensile structure|
In practice, structures tend to carry both tension and compression, and it is the degree to which a structure is intentionally tensioned to stabilise it that determines whether it is considered a tensile structure.
Tensioning, is usually achieved with wire or cable, opposed by compression elements such as masts, and held in place by foundations, ring beams, ground anchors and so on. Tensioning can also be achieved through inflation.
|Anticlastic (saddle-shaped).||Synclastic (dome-shaped)|
Doubly-curved surfaces can be tensioned without distorting their form, as the opposing curvatures balance each other at every point on the surface. Tensioning the fabric reduces its elasticity so that it will distort less when subsequently loaded, such as under wind load or snow load. In addition, the geometry of the curvature itself means that any extension of the fabric under load results in a relatively smaller deflection than would be apparent in a flatter, or less curved fabric.
For more on the structural behaviour, see The structural behaviour of architectural fabric structures.
