1 long-span multidirectional spatial structure;

2. High rigidity and good stability;

3. The bar mainly bears axial force, which can give full play to the strength of the material;

4. High-order static deformation with high safety;

5. The height of the structure is small, which can not only effectively use the building space, but also build a long-span structure with smaller bars;

6. The types of bars are unified, which is suitable for industrial production and integral lifting of ground assembly.

Advantages of truss structure:

1 node is simple. The structure is simple and smooth, and can be applied to various structural shapes.

2. High rigidity and good geometric characteristics. Generally, steel pipes have thin walls, large radius of gyration and good compression and torsion resistance.

3. Simple construction and material saving. The pipe truss structure has the advantages of simple construction and material saving because it abandons the traditional connecting members at the joints and directly welds all the members.

4. Conducive to rust prevention and cleaning and maintenance. The contact surface area between steel pipe and atmosphere is small and easy to protect. All components are directly welded at the joint, and there are no dead corners and grooves that are difficult to clean, paint, accumulate moisture and a lot of dust, which is more convenient for maintenance. After the entire length and end of the tubular member are closed, the inside of the tubular member is not easy to rust.

The tubular truss structure with circular tube section has good hydrodynamic characteristics. When subjected to loads such as wind or water flow, the influence of load on circular tube structure is much lower than that of other cross-sectional structures.
