The key point of the tensile membrane structure is to satisfy the technical requirements of the large-span free space, and the most important one is its effective space pre-tension system. Some people put the tensile membrane structure is called prestressed soft shell, is the pre-tension to make the soft shell parts (cable, film) under the most unfavorable load of the internal force is always greater than 0 (always in the tensile state), so that the soft shell becomes the overall work of the structure of the media and building materials, dual habitat in the building and structure of the two.

The key role of pre-tension in tensioned membrane structures is:

1, so that the tensile membrane structure of the building to smooth drainage.

2, so that the overall space structure system to work together.

3, so that the system to resist the wind, snow and other extremely unfavorable load conditions.

4, so that the system can cover a large area, large span of free space.

5, so that the film reduces wear and prolong the service life, become a permanent building.

6 So that the tensile membrane structure can be the roof of the building, for maintenance to provide convenient conditions.

7, so that the tensile membrane structure of the construction of attractive tension curve and unpredictable space.

Pre-tension is not in the construction process can be arbitrarily adjusted installation measures, but in the initial stage of the design needs to be repeatedly adjusted to determine, in the design and construction of the whole process must ensure that the core and key. In this sense, there is no careful design of the appropriate pre-tension measures of the membrane body covering, is not a tensile membrane structure of the construction category.
