What is membrane structure curtain wall? Membrane structure curtain wall is the application of membrane structure in the construction periphery, which has common characteristics and advantages of membrane structure: membrane structure is a new non-traditional structure form. A curved surface full of tension and variability, free and flexible large space, transparent, translucent film formed by the bright and soft indoor environment, mast, cable, exquisite metal joints embodied by the rich modern construction technology, these characteristics make the membrane structure for people to provide a different from the traditional structure of the new visual feeling, Offers unprecedented breadth of space and many new possibilities for architectural design, including architectural environment. Modern membrane structure technology in Germany, the United States, Japan and other developed countries have experienced more than more than 30 years of development, has now become mature. Architects have fully developed and exploited the possibilities offered by this new structure technology, and constructed many large membrane structures with typical significance, which embody the harmonious unification of architecture and structure, the perfect combination of technology and art. There are many membrane structure buildings to become a representative of the local cultural landscape.

The design of membrane structure is also different from the traditional structure. Only when the appropriate pretension is given to the flexible film, the shape and the stiffness of the external load can be determined, so the initial morphological analysis has the basic meaning in the membrane structure design. Cutting analysis is another special problem in the design of membrane structure: the surface shape of membrane structure is generally not fair, the cutting analysis is to require a reasonable lofting on the plane film to fit the corresponding bar on the surface of the space as accurately as possible. Moreover, the initial morphological analysis and cutting analysis of membrane structure is not only a simple mechanical problem or a technical problem; its initial form analysis is inseparable from the architectural modelling, and the pattern of the film patchwork is often an important interior decoration means and a powerful tool to express the interior space. Therefore, the design of membrane structure from the outset requires architects and structural engineers to work closely with each other. In fact, this novel system of architectural and structural solutions is a unified whole, should be combined together and completed.

The calculation and analysis of membrane structure has its particularity, for example: This flexible structure system has a large displacement, the geometrical nonlinearity must be considered in the calculation, the wind is the outer load which decides the function in the membrane structure design, the membrane structure is very sensitive to the dynamic action of the wind, it must be considered in the design calculation. Sometimes even further consideration should be given to the interaction between airflow and structure, that is, the so-called aerodynamic response problem.　　These characteristics increase the design difficulty of the membrane structure to some extent. The development of membrane structure and membrane structure curtain wall depends on the technological revolution and technology development of the membrane village, historically, the revolution of material technology brings more and more ideas to architecture, and also brings endless high demands. From modernism to postmodernism, to deconstruction architecture theory, even to the so-called chaos theory, the material revolution is invariably required, and every material revolution adds more new creation vocabulary to architecture. From the perspective of architectural color, through the building fa?ade of the color or nature to see the color of the interior, from light to dark or from dark to bright, architects can be based on the level of the layout, the color of the warm and cold arrangement, day and night light direction of the similarities and differences, to obtain their own architectural.

From the perspective of architectural aesthetics, with people's understanding and grasp of architectural beauty, the creation and development of architecture have been promoted from different angles. Good environment can inspire people's aesthetic feeling, good environment can also give people a sense of identity, intimacy, identification, culture and adaptability of different psychological feelings. Advances in materials technology can stimulate the heretical spirit in architectural creation, and can often be rationalized by the unreasonable design of this heresy, through the use of new materials. This heretical vision can be achieved by adopting an updated construction method. From the angle of architecture, the loose, disorderly, dislocation, odd insurance and accidental of deconstruction can get good nutrition in the progress of material science, penetrate into architectural culture, and appear the great miracle of blooming flowers and workmanship. Membrane structure, membrane structure curtain wall, membrane structure of the roof is the case.
