Membrane structure is a structural system that combines building and structure. It uses high-strength flexible film materials and auxiliary structures to generate a certain pre-tensioning stress inside in a certain way, and form a certain spatial shape under stress control as a covering structure Or the main body of the building, and has enough rigidity to resist the action of external load, a narrow structure type.
Membrane structure is a new type of architectural structure developed in the middle of the 20th century. It breaks the model of pure linear architectural style. With its unique beautiful curved shape, the combination of simplicity, liveliness, rigidity and softness, strength and beauty gives people The refreshing feeling also provides the architect with greater imagination and creative space. Membrane structure has a strong sense of the times and representativeness. It is a multidisciplinary cross-application engineering integrating architecture, structural mechanics, fine chemical engineering, material science, and computer technology. It has high technical content and artistic appeal. Its curved surface It can be changed arbitrarily with the architect's design needs. Combined with the overall environment, a landmark image project has been constructed, with strong practicability and a wide range of applications. It can be applied to large-scale public facilities, such as the roof system of stadiums, airport halls, exhibition centers, shopping centers, parking lots, platform facilities, etc. It can also be applied to leisure facilities, industrial facilities, entrance corridors, landmark or landscape buildings, sketches, etc.

Advantages of Tensile Membrane Structures
1. Flexible Design Aesthetics
Virtually unlimited designs of distinctive elegant forms can be
realized because of the unique flexible characteristics of
architectural membrane. Also, fewer support columns create more
functional, aesthetically pleasing spaces.
2. Outstanding Translucenncy
In daylight, the membrane's translucency offers soft diffused
naturally lit spaces reducing interior lighting costs. At night,
the artificial lighting creates an ambient exterior luminescence.
3. Shortened Construction Schedules
Incorporating the most modern construction techniques, large
fabricated membrane panels can be installed quickly to shorten
installation schedules. Likewise, fabric removal can be
accomplished easily.
4. Cost Beneifits
Lightweight structures can be a more cost effective solution than
traditional building materials offering building owners reduced
costs. Materials, such as photo-catalytic membranes, can help
prevent temperature rise as well as reduce maintenance costs due to
their self-cleaning properties.
5. Long Span Structures
Lightweight membrane is a cost-effective solution that requires
less structural steel to support the roof, enabling long spans of
column-free space.
6. Earthquake Resistant
Lightweight tensile membrane structures bear less building load
than traditional roofing materials and the membrane's elasticity
offers further earthquake resistance.
Classification:
The architectural structure of the membrane structure is colorful
and ever-changing. According to the support method, it is divided
into an inflatable membrane structure, a tensile membrane structure
and a skeleton support membrane structure.
1. Skeleton membrane structure
The roof skeleton made of steel structure or integrated material is
stretched above the membrane structure, and the lower support
structure has high stability. Due to the simple roof shape, the
opening is not easy to be restricted, and it has high economic
benefits. It is widely applicable For any large and small space.
2. Tensile membrane structure
It is composed of membrane material, steel cable and pillar, and
uses steel cable and pillar to introduce tension into the membrane
material to achieve a stable form. In addition to practicing
creative, innovative and beautiful shapes, it is also the most
structural form that can demonstrate the spirit of membrane
structure. Large-span spaces also mostly use steel cables and
compressed materials to form a steel wire mesh to support the upper
membrane. Due to high construction accuracy requirements, strong
structural performance, and rich expressive power, the construction
cost is slightly higher than the skeleton membrane structure.
3. Inflatable membrane structure
The inflatable membrane structure is to fix the membrane material
around the roof structure. After the indoor air pressure is raised
to a certain pressure by the air supply system, the pressure
difference between the inside and outside of the roof is generated
to resist the external force. Because the air pressure is used for
support, and the steel cable is used as an auxiliary material ,
Without any beam and column support, it can get more space, quick
construction and high economic benefit, but it needs to maintain
the 24-hour blower operation, which is higher in the cost of
continuous operation and machine maintenance costs.
