The world's first inflatable membrane structure was built in 1946 and was designed by W. Bird of the United States, a 15 inch diameter inflatable dome. The first International Inflatable Structure Conference held in Stuttgart, Germany in 1967 undoubtedly injected stimulants into the development of the inflatable membrane structure. A variety of inflatable membrane structures were then exhibited at the 1970 Osaka World Expo. Among them are the Geiger design of the American Pavilion (137m × 7m8 oval), and the sausage-shaped inflatable member membrane structure designed by Kawaguchi. Later, it was thought that the 70-year Osaka Expo was the beginning of systematically and commercially introducing the membrane structure to the outside world. The Osaka Expo demonstrates that people can build permanent structures with membrane structures. In the early 1970s, the Teflon membrane material developed by Geiger-Berger Associates in accordance with the US permanent building code laid the material foundation for the wide application of membrane structures to permanent and semi-permanent buildings. . Later, the indoor inflatable membrane structure made of Teflon material appeared in large and medium-sized gymnasiums, such as the "Silver Dome" (elliptical 220×159m) of Pontiac, Michigan, built in 1975. It was built in 1988. Tokyo Stadium, Japan (net area 4,6767 m2). The pioneer of the tensioned membrane structure is Germany's F. Otto. In 1955, he designed a tensile membrane structure with a span of about 25 m, which was used in the joint park multi-purpose exhibition hall. Since the tensioned membrane structure exerts a certain pre-tensioning stress on the membrane material through the boundary conditions to resist the external load, the initial shape is determined under certain initial conditions (boundary conditions and stress conditions) under the external load. A series of complex problems such as stress distribution and deformation in the film and how to simulate three-dimensional space surfaces with two-dimensional touch materials require calculation to determine, so the development of tensioned membrane structure is inseparable from the advancement of computer technology and new The proposed algorithm. At present, some advanced foreign touch structure design and production software has been perfected. People can see the shape and deformation under various initial conditions and external loads through the graphic display, and can calculate the stress state at any point to make the shape (the initial shape). The integration of analysis, cutting and force analysis makes the design of the membrane structure much simpler. It can not only analyze the stability of various structures and the stress in the membrane during the whole construction process, but also accurately calculate the adjustment cable or column. The secondary stress generated can completely avoid the unpredictable consequences of various unfavorable load conditions. Therefore, the rapid development of computer technology has opened up a broad prospect for the application of tensioned membrane structure. The successful development of Teflon materials has also greatly promoted the application of tensioned membrane structures.
