Pneumatic Structures

Pneumatic Structures are a specific type of structure characterized by slightly higher pressure of internal air above the outside pressure.

The weight of the roofing membrane is balanced and maintained by air compressors or fans or blowers.

The roof membrane of the pneumatic structure is made from rubber, or reinforced films using industrial fabrics coated with polymers.

In short, pneumatic structures are nothing else, but a membrane structure that is stabilized by compressed air pressure and has a tensile skin.

It is a very light enclosed structure usually fabricated from a membrane of impermeable material and supported by a difference in air pressure between the exterior and the interior of the structure.

Fans or compressed air or blowers must maintain an internal pressure slightly higher than normal atmospheric pressure to prevent the structure from slowly deteriorating and collapsing.

Types of Pneumatic Structures:

Air-supported structure:

 It is a structure in air of width under direct pressure under envelopes or membranes.

The average life of an air- supported structure is 20 to 25 years.

The cost of such a structure is relatively low.

There is a simplicity in design and construction. It has the flexibility to use the facility for seasonal activities.

The air-supported structure can be used for sports stadiums in which “bubbles” were used to cover tennis courts and swimming pools, and are also used for many other temporary structures.

Air-Inflated structure:

It is the structure in which air under high pressure is filled only by the supporting elements of the structure.

The capability of such a structure is self-supported.

There is no restriction on the number and size of openings and design geometries.

These structures can be used for sheds, shelters, bespoke buildings, permanent roofing and storage.

Advantages of pneumatic structures:

Following are the various advantages of pneumatic structures:

  1. It is a lightweight structure.
  2. There is a possibility to cover large spans without internal support.
  3. There is an rapid assembly of structure.
  4. Complete predetermination for light and radio waves, portability, transparency.
  5. It is a low cost structure.

Disadvantages of pneumatic structures:

Following are the various disadvantages of pneumatic structures:

  1. There is the need for continuous maintenance of excess pressure in the envelope or enclosed membrane.
  2. It has a relatively short service life.
  3. It has poor fire resistance and acoustic insulation.

Uses of pneumatic structures:

Following are the various uses of pneumatic structure:

1. It can be used for permanent. and temporary buildings for a variety of purposes such as production and storage areas, as well as halls for performance, sports stadium like tennis, swimming pool, trade or exhibitions.

2. It can also be used for mobile buildings such as maintenance station, medical aid stations, clubhouses, libraries.

3. It can also be used for hangars and shelters at airport areas.

Frequently Asked Questions:

What is pneumatic and how does it work in construction?

A pneumatic system is a system that uses compressed air to do work; they capture air, transport it around a circuit, and carry out specified tasks with the energy generated.

When invented pneumatics structure?

German physicist Otto von Guericke (1602 to 1686)

Where are pneumatics used?

Pneumatic systems are most commonly used in construction, factories, mills, and other areas

What is surface structure in construction?

A surface structure is made from a material that has a much smaller thickness than its other dimensions.

Conclusion:

The pneumatic structure is an environmentally friendly system that has extensive functions not only to the architectural discipline but also to various others.

The potential of those buildings might be broadened with the development of technology and might be integrated for various uses and situations.
