Due to the characteristics of the air membrane structure itself is different from the general traditional structure, in order to ensure the safety and beauty of the air membrane structure, Beijing Xinyuan Yijia Membrane Structure Technology Co., Ltd. must go through the following four steps when designing the air membrane structure building.

First, Architectural scheme design
The design scheme of the air membrane building needs to take into account the functional requirements of the project, the surrounding environmental conditions and the preference requirements of the owner. In addition to the above factors, the preliminary design scheme also needs to consider economic factors and construction technology and other technical conditions.
Second, form finding analysis
Because there is no flexural stiffness of the membrane material itself, the shape of the surface corresponds to the magnitude and distribution of the prestress value one by one. Therefore, after the control point coordinates are determined, a reasonable prestress value and distribution can be given to determine the appropriate shape of the membrane surface.
The size and distribution of the prestressed value is determined comprehensively after repeated adjustment according to various conditions, which is called form-finding analysis. This process is inseparable from the program design process.
Third, Load analysis
The control load of aerated membrane structure is usually wind load and snow load. Under the action of loads, the deformation of the membrane structure is large, so it is necessary to accurately calculate the deformation and stress distribution of the air membrane structure, so as to select the type and size of the cable, membrane and other materials, and determine the detailed joint method and construction measures.
Fourth, tailoring analysis
Cutting analysis is to find a reasonable cutting line position on a surface under prestressed state, and then expand the three-dimensional surface into a two-dimensional plane according to a certain method. In order to make full use of the membrane material and avoid unnecessary waste, it is generally cut according to the width of the membrane material. It should be noted that the curvature change of the membrane surface should be taken into account when cutting.
The design scheme of the air membrane structure is never a simple drawing, it is after repeated consideration and careful calculation. Understanding these design processes of Xinyuan air membrane, I believe you will be more confident in the safety of air membrane structure!
