What is the principle of air-supported membrane structure? How long is the life of the air-supported membrane structure?

With the continuous development of membrane structure technology, more and more fields are beginning to use membrane structure buildings. Air-supported membrane structure is very popular because it is safe, reliable, economical, comfortable to use, flexible and convenient. So, what is the principle of the air-supported membrane structure?  How long is the life of the air-supported membrane structure?  Let's take a look with Wanhao membrane structure.

The air-supported membrane structure refers to a building structure system that uses a special architectural membrane as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the membrane and support the main body of the building.

Working principle of air-supported membrane structure

A complete air-membrane building system also includes a lighting system and an access control system.  It works as follows:

1. The air-supported membrane structure supports the entire building by the difference between the inside and outside.  Due to the flexibility of the material and the inherent effectiveness of the structure and the curved shape, there are no members that are bent, twisted and compressed.

2. There is no need for any frame or beam and column support inside, the span can reach 110 meters.

3. With the increase of atmospheric pressure, the oxygen content of the environment is increasing. Therefore, the pressure difference between the inside and outside of the air-supported membrane structure will not only have any adverse effects on the human body, but will help people to engage in sports activities or physical work. The internal and external air pressure difference is 250Pa, which is about 0.0025 atmospheres (corresponding to the difference in air pressure between the 1st and 9th layers of the normal building).

The air-supported membrane structure service life

The main determinants of the life of the air-supported membrane structure are as follows:

1. Air-supported membrane structure quality assurance promise.

Membrane manufacturers provide 15 years of free compensation for quality assurance, that is, if the membrane exhibits aging and quality problems within 15 years, the membrane production unit will provide free after-sales service.

2. The membrane material is selected according to the planning needs, and the permanent building can generally supply the service to 30 years.

The service life of the membrane is generally planned and selected according to the specifications of the building according to the specifications of the building.

3. The membrane should be selected according to customer requirements.

Membrane-related selection, especially in the special environment and environment of the external environment, the membrane manufacturer will carry out special processing according to the requirements of customers.  Such as temperature range, color, light and opacity, tensile strength, impact resistance and so on.  The detailed situation is generally selected and recommended by the planning unit according to the service life.

4. The conclusion

The ultra-long-span air-supported membrane structure can last for more than 25-30 years, and the latest technology is the air-supported membrane structure construction technology with full stress relief system (inclined mesh cable system).  Because the long-term pressure peak of the membrane is smaller, the service life of the membrane can extend for 5-8 years, which extends the service life of the membrane structure.

If the design and materials of the smaller span of the membrane structure are properly used, the service life can be extended for a while.  The life of air-supported membrane structure building is more than 30 years, which is completely ok.

The above is the principle of the structure of the air-supported membrane and the detailed description of how long the life of the air-supported membrane structure is generally, I hope to help everyone.  If you have problems with membrane structure or membrane structure engineering, you can consult Wanhao space structure membrane.
