What Is Pneumatic Structures?
Important Point
Pneumatic Structures are the special type of structure which is generally characterized by the slightly higher air pressure of internal surrounding.
The word ‘Pneumatic’ means the structures which is constructed with the support of Air Pneumatic structures was introduced in the Building Technology about 40 years ago.
The pneumatic structure is a membrane structure which is stabilized with the help of the compressed air. The Pneumatic structures are a very cost-effective type of Buildings for the longer span.
The roof of the pneumatic structures are made from the rubber or enforce film with the help of polymers. The weight of the roofing membrane is balance and maintain with the help air compressors or blowers.
Pneumatic structures are environment-friendly structures. In the construction of the Pneumatic structures, the pressure difference between the enclosed space and the exterior is responsible for building for its shape and stability.
Pneumatic structures are the combination of two components with different properties which is an airtight membrane and compressed air.
One of the Disadvantages of the pure pneumatic structures is that it required high air pressure to maintain its shape. The pneumatic structures are generally made from the laminated membranes such as nylon, fibreglass polyester, silicon rubber etc.
The shape of the Pneumatic structure is round because it creates a larger volume for less amount of material. The pneumatic structure is a membrane which can carry the total load develop from the tensile stresses.
The stabilization of the Pneumatic structure is done with the help of pre-stressing of the membrane. The pre-stressing of the membrane is done by applying an external force to put the membrane.
Pneumatic architecture structures are used widely for the construction of permanent as well as temporary structures. Pneumatic structures can develop an artificial environment that is adaptable for humans. The foundation required for the Pneumatic structure is secured to the ground using Heavyweights.
The material which is used for the envelope is as follows.
- Fibreglass which has high tensile strength and durability
- Polyester or PVC coated polyester which is flexible.
- Nylon or vinyl-coated nylon which has more strength and durability.

Principle of Pneumatic Structures
- The principle of the Pneumatic structure is the use of a very thin membrane that is supported by a pressure difference.
- The Dead weight of the space available in the envelope is balanced by increasing the inside air pressure.
- The thin membrane gets stress to the point where it cannot be indented by the asymmetrical loading.
Types of Pneumatic Structures
There are mainly two types of Pneumatic structures
- Air supported pneumatic structures
- Air inflated pneumatic structures

1. Air Supported Pneumatic Structures
Air supported structures have Air higher than the atmospheric pressure supporting the envelope. Air supported inverter structures are supported by the internal air pressure and use of a network of the cable stiffen the fabric.
The lifespan of the Air supported structures is 20 to 25 years. The Air supported Pneumatic structures have a relatively low cost. The Internal pressure in the air-supported structures is maintained above the Normal atmospheric pressure with the help of compressors or fans.
It should be provided with Airlocks which are required to prevent the loss of internal air pressure.

2. Air Inflated Pneumatic Structures
Air inflated structures are supported by pressurized air which contained with an inflated building element. Air inflated structures are supported with the help of pressurized air within inflated building elements in the different shapes that will carry the loads.
In the air-inflated structures, the air under high pressure fills only in the supporting elements of the pneumatic structure. The internal pressure of the air Inflated structures remains at the atmospheric pressure.

A pneumatic structure system refers to a type of structural system that utilizes pressurized air or gas to create and maintain the shape and stability of a structure. It involves the use of airtight membranes or inflatable elements to form the structural elements, such as walls, roofs, or domes.
Air Supported Pneumatic Structures
An air-supported (or air-inflated) structure is any building that derives its structural integrity from the use of internal pressurized air to inflate a pliable material (i.e. structural fabric) envelope, so that air is the main support of the structure, and where access is via airlocks.
Types of Pneumatic Structures
Four types of pneumatic structure: Low positive pressure, high positive pressure, hybrid (low and high positive pressure), high negative pressure.
Innovative Applications of Pneumatic Structures
Pneumatic structures, also known as inflatable structures, have been used in various innovative applications due to their lightweight, flexible, and easily deployable nature. Here are some examples of innovative applications of pneumatic structures:
