What are the advantages of steel space frame structure compared to plane structure engineering?

Compared with the traditional plane structure engineering, the steel space frame structure has the following 6 advantages:

1. Due to the interaction between the space frame structural members, it has good integrity, large space rigidity and very stable structure.

2. The space frame structure relies on the axial force of the rods to transfer the load, and the material strength is fully utilized, which not only saves steel, but also reduces its own weight. A good space frame design has a steel content close to the steel content of a reinforced concrete structure under the same conditions, which can save a lot of concrete and reduce its own weight by 70-80%. Compared with ordinary steel structures, it can be Save 20-50% of steel.

3. Good seismic performance. Due to the light weight of the steel space frame structure, the seismic force generated during an earthquake is small. At the same time, the steel has good extensibility and can absorb a large amount of seismic energy.The space frame has high rigidity, stable structure and will not collapse, so it has excellent seismic performance.

4. The space frame structure is small in height. The space can be effectively used. The height-span ratio of ordinary steel structure is 1/8-1/10, while the height-span ratio of space frame project is only 1/14-1/20, which can reduce the height of the building.

5. The construction speed is fast. The components of the space frame structure have the same size and shape, which can be mass-produced in the factory, and are of good quality, high efficiency, and do not compete with civil engineering. Therefore, the on-site workload is small and the construction period is shortened.

6. The structure of the space frame is light. It can cover planes of various shapes, and can be designed into various shapes with beautiful and generous appearance.
