Prefabricated steel structure building: A prefabricated building whose structural system consists of steel components.

Steel structure is a natural prefabricated structure, but not all steel structures are prefabricated buildings, especially not good prefabricated buildings. So what kind of steel structure building can be regarded as a good prefabricated building? The steel structure, the enclosure system, the equipment and piping system and the interior system must be harmonious and unified in order to be regarded as an assembled steel structure building.

Compared with prefabricated concrete buildings, prefabricated steel structures have the following advantages:

1) Without on-site cast-in-place nodes, the installation speed is faster and the construction quality is more easily guaranteed;

2) The steel structure is a ductile material with better seismic performance;

3) Compared with the concrete structure, the steel structure has lighter weight and lower foundation cost;

4) The steel structure is recyclable material, which is more environmentally friendly;

5) The elaborately designed steel structure prefabricated building has better economy than prefabricated concrete building.

6) The beam-column section is smaller, and more usable area can be obtained.

Enclosure system is a key factor for prefabricated buildings. The steel structure system must cooperate closely and harmoniously with the enclosure system. For example, the frequently used square column + external wall panel system is a mature building structure system used in office buildings, but it will cause residents to have an adverse effect on prefabricated buildings because they are used to shear forces. The Chinese residents of the wall structure do not want to see beams and corner pillars indoors. In addition, structural issues such as the detailed handling of sound bridges are also key technologies for prefabricated steel structures.
