Membrane structure landscape The design includes four parts: shape design, initial balance shape analysis, load analysis and cutting analysis. After shape design, determine the building plane shape proportion, 3D modeling, clearance volume, confirm the coordinates and structure of each control point, and select membrane materials and construction plan.
Membrane structure design of membrane structure equipment mainly includes four main problems: shape design, initial balance shape analysis, load analysis and cutting analysis. After shape design, determine the building plane shape proportion, 3D modeling, clearance volume, confirm the coordinates and structure of each control point, and select membrane materials and construction plan. Initial equilibrium shape analysis is called shape analysis. Because the membrane material itself has no compression and bending stiffness, its shear strength is very poor, so it needs to improve its stiffness and stability through the curvature of the membrane surface and the prestress during its action. For membrane structure, it does not exist at any time. Because there is no stress, the curved surface shape of the membrane must meet the mechanical balance under certain boundary conditions and certain prestress conditions, and load analysis and shear analysis are carried out on this basis. The form finding analysis methods of membrane structures mainly include dynamic relaxation method, force density method and finite element method. The loads considered for membrane structures are usually wind and snow. The deformation of membrane data under load is relatively large, and the load distribution will change with the change of shape. Therefore, it is necessary to use some nonlinear methods to accurately calculate the deformation and stress of the structure.
The tensile membrane structure is supported by columns and steel frames or formed by steel cables. It consists of membrane materials, steel cables and struts, and uses steel cables and struts to introduce tension into the membrane materials to achieve a stable method. In addition to being able to practice creativity, innovation and beautiful shapes, it is also a construction method that can demonstrate the spirit of membrane structure. Steel wire ropes and compressed materials are also usually used to form steel wire mesh in large span spaces to support the upper membrane. The construction cost is slightly higher than that of skeleton membrane structure due to the high requirements for construction precision, strong structural performance and strong expressive force.
The inflatable membrane structure is to fix the membrane material around the roof structure. When the air supply system is used to increase the indoor air pressure to a certain pressure, the pressure difference between the interior and exterior of the roof will be generated to resist external forces. Since air pressure is used as support and steel cable as auxiliary material, no beam column support is required, so more space can be obtained, construction is convenient and economic benefits are high, but it needs to be maintained 24 hours of blower workload, which will increase the cost of continuous operation and machine maintenance.
