Membrane structure equipment The design of membrane structure mainly includes body shape design, initial balance shape analysis, load analysis, cutting analysis and other four major issues. Through figure design, confirm the building plane shape scale, three-dimensional modeling, clearance volume, confirm the coordinates and structural mode of each control point, select membrane materials and construction plan. Initial equilibrium shape analysis is called shape finding analysis. Since 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 membrane structures, there is no stress free state at any time, so the shape of the membrane surface must be satisfied with 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 changing with the change of shape, so several nonlinear methods are used to accurately calculate the deformation and stress of the structure.

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. The steel cables and pillars are used to introduce tension into the membrane materials to achieve stability. In addition to practical, creative and beautiful shapes, it is also a structural way to show the spirit of membrane structure In large span spaces, steel cables and compressed materials are often used to form a steel cable network to support the upper membrane materials. The construction cost is slightly higher than that of skeleton membrane structure due to high construction precision requirements, strong structural performance and rich expressiveness.

The inflatable membrane structure is to fix the membrane material around the roof structure, use the air supply system to raise the indoor air pressure to a certain pressure, so that there is a pressure difference between the inside and outside of the roof to resist external forces. Because of the use of air pressure to support, and the use of steel cables as auxiliary materials, without any beam, column support, it can get more space, convenient construction, and high economic benefits, However, it is necessary to maintain the blower for 24 hours, and the cost of continuous operation and machine maintenance is high.
