Membrane structure is a structural system that combines architecture and structure. It uses high-strength flexible film materials and auxiliary structures to generate certain pre-tension stresses 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 a type of narrow structure with sufficient rigidity to resist external loads. Membrane structure is a new type of building structure developed in the middle of the 20th century. It breaks the pattern of pure linear architectural style. With its unique beautiful curved shape, it is simple, crisp, rigid and soft, and the combination of strength and beauty. Refreshing feeling, while providing architectural designers with greater imagination and creative space. Membrane structure has a strong sense of time and representativeness. It is a multi-disciplinary cross-application project integrating architecture, structural mechanics, fine chemical engineering, material science, and computer technology. It has a high technical content and artistic appeal. Its curved surface Can be arbitrarily changed according to the architect's design needs. Combined with the overall environment, the iconic image project is built, with strong practicability and wide application fields. It can be applied to large public facilities, such as the roof system of stadiums, airport halls, exhibition centers, shopping centers, parking lots, platform facilities, etc. Advantages: (1) Large span. Membrane structure has light weight and good seismic performance, which can eliminate the need for internal support. It overcomes the difficulties encountered by traditional structures on large-span (unsupported) buildings. It can create huge unobstructed visual space and effectively increase the space used. . (2) Artistic. Membrane structure breaks through the traditional architectural structure types, relying on styling and color science, can combine natural conditions, give full play to the architect's imagination, and create curves and various shapes that are difficult to achieve in traditional buildings according to creativity. , Full of the atmosphere of the times, reflecting the beauty of the strength of structural members. With the light, it is easy to form a night scene, giving people the enjoyment of modern beauty. (3) Economical. The film material has a certain light transmittance, which can reduce the intensity and time of lighting during the day and save energy; the transmission of colored lights at night can form a gorgeous landscape. Moreover, the membrane structure can be disassembled and easy to relocate, especially when building large-span buildings for short-term applications, which is more economical. (4) Security. The flame retardant and high temperature resistance of the membrane material can well meet the fire protection requirements; the membrane structure is a flexible structure that can withstand large displacements and is not easy to collapse; the membrane structure has light weight and good seismic performance. (5) Self-cleaning. Membrane materials with protective coating are used in membrane construction, which is not sticky. The dust falling on the surface of the membrane material can be washed by rain to achieve a good self-cleaning effect, while ensuring the service life of the building. (6) The construction period is short. The cutting of the diaphragm, the production of steel cables and steel structures, etc. are all completed at the factory to reduce the construction time on site. It can be carried out simultaneously with the lower reinforced concrete structure or components to avoid construction crossovers. At the construction site, only the steel cables, steel structures and membranes The connection, installation and positioning of the film and the process of tension, so the site construction and installation is fast and fast, and the construction period is relatively short compared to the traditional construction project. (7) Wide application. From the perspective of climatic conditions, membrane structure buildings are suitable for a wide area; from the perspective of scale, they can be as small as a single tent, a garden sketch, or a building covering tens of thousands or hundreds of thousands of square meters. Some people even imagined covering a small city to realize artificial nature. 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. sive, one will have to think about the long-term advantages.

Pre Engineered Steel Buildings Conventional Structural Steel Buildings
1) Design Criteria ISO Universal 1) Design Criteria normal domestic standard
2) Design: Quick and efficient since standardization of pre-engineered steel buildings has significantly reduced design time. Basic designs are used over Specialized computer analysis and design programs reduce design time and optimize material required. Drafting is also computerized with minimal manual drawings. Design, detail drawings and erection drawings are supplied free of charge by the manufacturer. Approval drawings may be prepared within ten days to 3 weeks. Consultant in-house design and drafting design is significantly reduced, allowing more time for coordination and review, and increasing margins in design fee savings. 2) Design: Each conventional steel structure is designed from scratch by the consultant, with fewer design aids available to the Engineer. Maximum engineering required on every project. Generalized computer analysis programs require extensive input/output and design iterations. Drafting is manual or only partially automated. Much Consultant time and expense is devoted to design and drafting, as well as coordination and review.
3) Weight: About 30% lighter through the efficient use of steel. Primary framing members are designed with tapered built-up plate sections with the most steel in the areas of highest stress, using high strength steel. Secondary members are light gage cold formed “Z” or “C” shaped members. Members are roll-formed for minimum weight and labor cost. 3) Weight: Steel member sizes must be selected from standard hot rolled sections, which in many cases are heavier than what is actually required by design. Members are the same cross-section along the entire length, regardless of local stress magnitude Secondary members are from standard hot rolled “I” and “C” sections. In many cases members are heavier than required, and therefore are not as economical as cold formed members.
4) Base Material: Rigid Building pre-engineered steel buildings system uses almost all steel to meet 50,000 P.S.l. minimum yield including the cladding. 4) Base Material: In most of the cases (90%) Base Material is 36,000 P.S.I. minimum yield.
5) Foundation: Simple design, easy to construct and lightweight. 5) Foundation: Extensive heavy foundation required.
6) Accessories (Windows, Doors, Ventilation): Designed to fit the system, with standardized, interchangeable parts, including pre-designed flashing and trims. Mass produced for economy. All available with the building. 6) Accessories (Windows, Doors, Ventilation): Every project requires special design for accessories and special sourcing for each. Flashing and trims must be uniquely designed and fabricated.
7) Delivery: much faster 7) Delivery: longer time
8) Erection: Easy, fast, step by step. Erection costs and time are accurately known, based upon extensive experience with similar buildings. 8) Erection: Slow, extensive field labor required. Typically 20% more expensive than pre-engineered steel buildings.In most of the cases, the erection cost and time are not estimated accurately.
9) Architecture: Outstanding architectural design can be achieved at low cost. Conventional wall and fascia materials, such as concrete, masonry and wood, can be utilized. 9) Architecture: Special architectural design requires research and high cost.
10) Overall Price: Price per square meter may be as much as 40% lower than conventional steel. 10) Overall Price: High price per square meter.
11) Sourcing and Coordination: Building is supplied complete with cladding and all accessories, including erection if required, all from one source of supply. 11) Sourcing and Coordination: Many sources of supply. Project Management time required to co-ordinate suppliers and sub-contractors.
