Tensioned Membrane structure is a structural system consisting of building fabrics, i.e. membrane materials, as the main tensioning body, and supporting members or cables. It has become one of the main forms of large-span spatial structures because of its novel and unique architectural shape and good mechanical characteristics. Membrane material refers to the construction textiles with stable shape and certain load, which are made up of polyester fiber substrates or different surface coatings such as PVDF, PVF, PTFE and high quality PVC. Its life varies with different surface coatings and can generally reach 12-50 years.
Characteristics and application fields of membrane structure buildings:
Membrane structure is a new form of building structure. It integrates architecture, structural mechanics, fine chemical industry, material science, computer technology and so on. It has high technical content. Its surface can be changed arbitrarily with the architect's design needs, combined with the overall environment, to build a landmark image project.
Artistry: Give full play to the imagination of architects, and reflect the beauty of clear force on structural components.
Economy: Because the film has a certain transmittance, daytime lighting intensity and time can be reduced, and energy can be well saved. At the same time, the gorgeous landscape formed by night color lamp transmission can also achieve good advertising and publicity benefits.
Long-span: Membrane structure can overcome the difficulties encountered by traditional structure in long-span (unsupported) buildings fundamentally. It can create huge visible space without occlusion and effectively increase the space usage area.
Self-cleaning: Membrane with protective coating is used in membrane building, which can make the building have good self-cleaning effect and ensure the service life of the building.
Short construction period: All processing and production in membrane construction projects are completed in the factory, which can reduce the construction time on site and avoid construction overlap. Compared with traditional construction projects, the construction period is shorter. Membrane building can be widely used in large public facilities: roof system of stadium, Airport hall, exhibition center, shopping center, platform, etc. It can also be used for leisure facilities, industrial facilities and landmark or landscape architectural sketches.
First, what is membrane structure?
Membrane structure, also known as Tensioned Membrane structure, is a structural system composed of building fabrics, i.e. membrane materials as the main tensioning body, and supporting members or cables. It has become one of the main forms of large-span spatial structures with its novel and unique architectural shape and good mechanical characteristics. Membrane structure is a perfect combination of architecture and structure. It is a kind of space structure which combines high-strength flexible membrane material with supporting system to form a stable surface with certain stiffness and can bear certain external loads. It has many advantages, such as free and lightweight shape, flame retardant, simple manufacture, fast installation, easy to use and safety, so it has been widely used all over the world. This structure is especially suitable for large stadiums, population corridors, sketches, public recreation plaza, exhibition venues, shopping malls and other fields.

2. Characteristics of membrane structure buildings:
Light weight: Membrane structure is a light structure because of the material and structure used in the membrane structure. Compared with other traditional architectural forms, the membrane structure is very light. Long life: Membrane structure is a semi-permanent building. The earliest membrane structure in the world has been used for more than 30 years and is still in use. Its steel skeleton can be used permanently as long as it is well coated and maintained in time. Membrane used in building is a kind of advanced composite material, which has good mechanical properties, high strength and aging resistance. As long as the structure design is reasonable, the safe service life of membrane structure building can be up to 50 years. Self-cleaning: The surface of membrane material used in building has no static electricity and no adsorptive force to dust, so it is not easy to get dirt, even if a little dust falls, it is easy to be removed by wind and rain. Therefore, membrane structure architecture always appears in our vision with bright and clean surface. Long-span: Large-span buildings without intermediate supporting columns, some large public places, stadiums and gymnasiums are required to form a large area of open space without columns, which poses a big problem for architects. With membrane roofs, the problem is greatly simplified. Because the membrane per unit area is very light, it greatly reduces the weight of the skeleton. If necessary, a very light roof can be supported by a small pressure difference between indoor and outdoor air. Good workmanship: Membrane is a complex space surface which is difficult to manufacture by rigid materials. It is much more convenient to use membrane structure. Membrane can be supported by steel skeleton, or can be stretched by cable to generate a variety of spatial surfaces. The surface generated by the membrane structure is smooth and soft, and it can clearly reflect the beauty of the mechanical forming of the membrane. Short construction period: skeleton production and fabrics processing are carried out in the factory, thus greatly shortening the construction period of the site, alleviating the situation of multi-type cross-work and mutual interference on the site.
