The planning of membrane structure facilities mainly includes four major issues: shape planning, initial balance shape analysis, load analysis, and cutting analysis. After figure planning, confirm the plane shape scale, three-dimensional modeling and clearance volume of the building, confirm the coordinates and structural mode of each control point, and select membrane materials and construction scheme. Initial equilibrium shape analysis is called shape finding analysis. Because the membrane data 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 between them. For the membrane structure, there is no stress free condition at any time, so the shape of the membrane surface must meet the mechanical balance under certain boundary conditions and certain prestress conditions, Based on this, load analysis and cutting analysis are carried out. Dynamic relaxation method, force density method and finite element method are the main methods for form finding and analysis of membrane structures. The loads considered for membrane structures are generally wind load and snow load. The deformation of membrane data under load is large, and the load distribution is also changing with the change of shape, so the deformation and stress of structure should be accurately calculated by geometric nonlinear method.

The tensioned membrane structure is supported by columns and steel frames or tensioned by steel cables. It is composed of membrane materials, steel cables and pillars. Tension is introduced into the membrane materials by steel cables and pillars to achieve stability. In addition to practical, innovative and beautiful modeling, it is also a structural way to show the energy of membrane structure The large span space also adopts the method of supporting the upper membrane materials with a steel cable net composed of steel cables and compressed materials. Due to the high construction precision requirements, strong structural performance and rich expressive force, the cost is slightly higher than that of skeleton membrane structure.

Membrane structure sunshade The shed is a kind of construction used as a barrier to protect vehicles from damage. It mainly serves as a shelter from the wind and rain. The membrane structure shed is also a valuable work of art. Give people beautiful visual enjoyment. Its softness, its curve, its hardness and softness, its rich shape, its white and flawless, make people look bright and have a long aftertaste. It is often found in companies, institutions and various public places. It is divided into single shed and double shed. Generally, there are two steel frames for the base of single type shed; The double shed is determined according to the condition of the parked vehicles. The frame of the small car shed is composed of 2-5 steel frames, and the large and medium-sized ones are composed of 6-10 or more. Beautiful and generous, what's more, it has high strength, high durability, anti ultraviolet and heat insulation effects.
