Gas film building is mainly used for gas film Pavilion, gas film shed, gas film building, gas film coal yard, gas film coal shed, air film tennis hall, air film gymnasium, air film basketball hall, air film stadium, inflatable membrane structure, inflatable membrane building, inflatable membrane gymnasium, etc.
Before the construction of each building, the designer should make a comprehensive plan for the problems existing in the construction process or in the use process according to the construction task. The same is true for inflatable membrane buildings. What are the design standards for inflatable membrane buildings?
1. The internal pressure produced by the air membrane structure components and its accessories must be less than their respective allowable stress and allowable resistance under all the anticipated loads.
2. The membrane structure system must be safe and not exceed the allowable deformation under all the expected loads.
3. The allowable stress or resistance of membrane materials, ropes and their connecting parts is the value obtained by dividing the respective strength by the appropriate safety factor. The determination of safety factor should take into account the aging characteristics of material strength, the type of connection nodes, the planned use period, and environmental factors, which are determined according to the actual situation.
4. Under the load with slight frequency and short duration, the safety factor can be reduced according to the actual situation. However, the safety factor should not be less than 2
5. The allowable deformation of structure must fully meet the requirements of building function.
6. The allowable deformation under the load with low frequency and short duration must be able to maintain the soundness of the structure and not become an obstacle for emergency evacuation at dangerous time.
