Tension membrane structure The design of is mainly composed of four themes: shape design, initial balance shape analysis, load analysis and cutting analysis. The initial equilibrium shape analysis is called form finding analysis. Under the external load, the stress in one direction increases and the stress in the other direction decreases, which requires the degree of initial tensile stress to be met. At present, the stress under load will not decrease to zero, that is, there will be no wrinkles. Under the load, the deformation of the membrane material is large, and the load distribution changes with the shape. Therefore, in order to accurately calculate the deformation and stress of the structure, the geometric nonlinear method should be used.

  At present, there are mainly dynamic relaxation method, force density method, finite element method, etc. Because the membrane material is soft and its natural vibration frequency is low, it is easy to generate wind vibration under the wind load, which will lead to damage of the membrane material. If the initial prestress is too high, the membrane material coating will become larger, easy to age, and the strength reserve is less. The strength requirements for stressed members are also high, which increases the difficulty of construction and installation.

The manufacturing principle of membrane structure is to ensure its beauty and also have strong durability, which is mainly reflected in its own characteristics.

  However, the membrane structures displayed in front of us are very artistic. This art is due to cutting. When manufacturers produce membrane structures, they do not produce membrane structures or have various shapes, but they are manually cut by people. I believe that membrane structure will be more and more widely used in future life.
