Membrane structure landscape Why can we design different shapes? The ceiling material used in membrane structure engineering is tensile membrane, which is a high-strength flexible material that can be spliced and welded.

The fixed membrane structure can be designed into different structural styles according to the needs of the owner.

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.

Because the membrane material itself has no compression and bending stiffness, and its shear strength is 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 must finally meet the mechanical balance under certain boundary conditions and certain prestress conditions, Based on this, load analysis and clipping analysis are carried out.

The main form finding methods of membrane structures include 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 accurately calculated by geometric nonlinear method. Another purpose of load analysis is to determine the initial pretension in cables and membranes.

Features of membrane structure:

Free building shape

The changeable supporting structure and flexible membrane material make the building more diversified and beautiful, and at the same time, it reflects the beauty of the structure, and has rich colors, which can create more free building shapes and richer architectural language.

Good economic benefits

The weight of membrane building roof is only one thirtieth of that of conventional steel structure roof, which reduces the cost of walls and foundations. At the same time, the new, strange, special shape and night view effect of membrane building have obvious "building visibility" and commercial effect, and its price benefit ratio is higher.

Short construction period

The processing and fabrication of steel structure members in the membrane structure project can be completed in the factory of Lianxin Steel Structure Co., Ltd. according to the design, and only the installation work can be carried out on the site. Compared with the construction cycle of traditional buildings, it is almost twice as fast.

Low energy consumption

The film material has higher reflectivity, lower light absorption and lower thermal conductivity, which greatly prevents solar energy from entering the room. In addition, the translucency of the membrane material ensures that the appropriate natural diffuse light provides sufficient light for the interior.
