As we all know, membrane structures are widely used in today's society. They are divided into landscape type and tent type, and their production processes are also different. Let's take a look Membrane structure landscape Compression and bending stiffness problems
The design of membrane structure landscape mainly includes four major issues: figure design, initial balance shape analysis, load analysis, and cutting analysis. Determine the plane shape, size, 3D shape and clearance volume of the building through figure design, determine the coordinates and structural form of each control point, and select membrane materials and construction scheme. Initial equilibrium shape analysis is called form finding analysis.

Since the membrane material itself has no compression and bending stiffness, and the main shear strength is very poor, its stiffness and stability need to be improved by the curvature change of the membrane surface and the prestress in it. For membrane structures, there is no stress free state at any time, so the shape of the membrane surface. It is required to meet the mechanical balance under certain boundary conditions and prestress conditions, and carry out load analysis and cutting analysis based on this.
At present, the main form finding methods of membrane structures are dynamic relaxation method, force density method and finite element method. The loads considered for membrane structures are generally wind load and snow load. The deformation of membrane material under load is large, and the load distribution is changing with the change of shape, so the deformation and stress of the structure should be calculated by geometric nonlinear method.
