A Fabric Revolution: The Basics of Fabric Buildings
Fabric structures, tension fabric structures, or tensile structures are distinct from conventional construction materials and techniques. They include a load-bearing structure usually in the form of steel cladding or aluminum, and a tensile fabric. This material, usually PVC-coated polyester or PTFE-coated fiberglass, is tensioned across the frame to form a sleek and effective structure.

The nature of fabric structure makes these them highly versatile. This makes it possible for large clearspan fabric structures to be created because few internal supporting columns are necessary. Also, the fabric is translucent and allows sufficient natural light to penetrate the building, thus eliminating artificial lighting during the day.
Types of Fabric Buildings
1. Tensile Structures
Tensile structures are recognized by employing the tensioned fabric membrane spanning between lightweight support structure. Due to the tensile nature of the fabric it is capable of withstanding certain environmental loads like wind and snow loads. These structures can be of any shapes, ranging from mere curved designs to designs such as the hyperbolic paraboloids. Tensile structures are commonly incorporated into architectural designs for its aesthetic value and versatile forms.
2. Air-Supported Structures
Air-beam structures depend on a vacuum or pressure being created to support the structure’s form. It is mostly made up of PVC or ETFE (ethylene tetrafluoroethylene) fabric membrane and has numerous benefits and drawbacks.

These structures can be easily inflated and deflated, which makes them ideal for transient or relocatable situations. They have large uninterrupted ceiling spans and are applied in the construction of sports complexes, exhibition centers, and temporary shelters.
3. Frame-Membrane Structures
The frame-membrane structures consist of rigid steel or aluminum frame on which a fabric membrane is stretched. The frame is mainly for the support of the structure and the shape of the building while the fabric offers the protection from the weather and the natural light. These buildings can vary in size and form and their uses can range from industrial storage, from workshops to manufacturing plants.
4. Cable-Net Structures
Cable-net structures rely upon a system of tensioned cables for the support of the fabric membrane. The cable grid spreads the loads evenly and also provides the feeling of an open and vast interior. It is widely applied in construction of large-span buildings such as sports stadiums, convention and exhibition centers, and terminals of airports. Thus, the architectural form created can be dramatic and instantly recognizable.
5. Pneumatic Structures
These structures utilize the pressure of air within separate compartments to achieve a segmental look. These structures are also very light, can be easily transported, and are not very time-consuming to put up. They are intended for short-term uses such as in disaster relief, as emergency shelters and other novel structures where the inflatable look is appropriate.
6. Sail Structures
Sail structures copies the elegant curves of sails of a ship. The fabric is stretched between the masts or poles to form an aesthetically pleasing and a practical shading system. Sail structures are widely used in outside areas such as plazas, courtyards, and theaters and serve both a shading function as well as an aesthetic one.
7. Modular Fabric Buildings
Modular fabric buildings are made up of specifically designed modules that can be easily installed.
