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

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

After figure planning, determine the plane shape scale, three-dimensional modeling, clearance volume of the building, determine the coordinates and structural form of each control point, select membrane materials and construction plan.

Because the membrane data itself has no compression and bending stiffness, and the 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 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.

The methods of form finding and analysis of membrane structures mainly 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 data under load is large, and the load distribution is also changing with the change of shape. Therefore, to accurately calculate the deformation and stress of the structure, several nonlinear methods should be used. Another purpose of load analysis is to determine the initial pretension in the cable and membrane.

Features of membrane structure:

Free construction, shape and image

The changeable supporting structure and flexible membrane material make the building more diversified in shape and beautiful in new style, which together represent the beauty of structure and rich in color, and can create more comfortable building shape and richer building language expression.

Good economic performance

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

Short construction period

The processing and manufacturing of steel structure members in the membrane structure project can be completed in the factory of Lianxin Steel Structure Company according to the plan, and only the device operation can be carried out on the site. Compared with the construction period of traditional construction, it is almost twice as fast.

Low power loss

The film material has higher reflectivity, lower light absorption and lower thermal conductivity, which to some extent 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.
