Air dome tent safety analysis

As a new type of building structure, air dome tent has attracted more and more attention because of its unique advantages and wide application. This article will start from four aspects, in-depth analysis of the safety of the air dome tent, so that you can buy with peace of mind, with peace of mind.

1. Wind resistance

On the contrary to conventional buildings, air dome tent produce a lifting force, so we will carry out different fixed designs according to the different wind speeds in different places. Conventional air dome tent wind resistance in 10-12 level, we will use anchoring system for ground fixation.

At the same time, the firm material is laid with diagonal mesh steel cable to improve the stability of the air dome tent. Ensure that under the action of the local maximum wind load, the maximum displacement of the film material does not exceed 10 cm, which is difficult to detect by the naked eye.

During the design process of the air dome tent, we will conduct simulated wind tunnel tests to further ensure its wind resistance.

2. Snow resistance

As a flexible building, the air dome tent has a strong immunity to external forces such as earthquakes, but it also reflects its weak side for strong winds and heavy snow. Under the combined effect of wind and snow, the snow is easy to gather to a certain part, forming the "bag effect" said in the membrane structure industry, so that the structure collapses. In order to avoid the bag effect, it is necessary to increase the internal pressure of the air dome tent as much as possible, so that the air dome tent becomes rigid. However, the pressure in the film is not infinite, and it is easy to reach the withstand limit of the film material, so the steel cable is needed to bear the force.

Our air dome tent greatly increases the pressure in the film through the inclined mesh steel cable system, turning the flexible building into a rigid building, and no longer swaying and deforming under the action of the outside wind and snow, thus improving the safety performance.

3. Earthquake resistance

The earthquake resistance of the air dome tent comes from its lightweight and flexible structural design. When the film material shakes and deforms during an earthquake, it can absorb and offset a large amount of earthquake energy. The weight of the air dome tent is very light, which greatly reduces the destructive power of the earthquake. Through a large number of technical experiments and CFD numerical analysis methods, technicians can simulate the impact of seismic waves on air dome structures.

4. Fireproofing

The film material used in the gas film building has good flame retardancy, can meet the requirements of B1 level fire prevention, no open flame does not burn, and automatically extinguishes when leaving the fire source. This means that in the event of a fire, the membrane can delay the spread of the fire and provide more time for evacuation and rescue. In addition, the interior of the air dome tent is usually equipped with fire protection facilities such as smoke alarms and spray equipment to further improve its safety.

When a fire occurs, the film may be burned out by open fire, but because of the positive pressure inside the gas film, the smoke will be quickly squeezed to the break and discharged outside, greatly reducing the harm of the fire. Even if it encounters a strong fire, it can ensure that the time of the membrane to fall to 3 meters on the ground is greater than 34 minutes, ensuring the evacuation time of personnel.

In summary, the air dome tent has excellent performance in wind resistance, snow resistance, shock resistance and fire resistance, and has high safety. However, in order to ensure the safety and security of the air dome tent, we still need to strengthen maintenance and inspection during use, and timely discover and deal with potential safety hazards.
