A new type of building system of steel structure building has the industry boundaries between the real estate industry, construction industry and metallurgical industry, and is integrated into a new industrial system. This is the steel structure building system that is generally optimistic about the industry.
Compared with traditional concrete buildings, steel structure buildings replace reinforced concrete with steel plates or profiled steels, which have higher strength and better earthquake resistance. And because the components can be manufactured in factories and installed on site. Therefore, the construction period is greatly reduced. Due to the reusability of steel, construction waste can be greatly reduced, and it is more green and environmentally friendly. Therefore, it is widely used by countries all over the world and is used in industrial buildings and civil buildings.
Take the stadium space frame as an example. The stadium refers to a 400-meter runway (including a football field in the center) with fixed road teeth. Outdoor track and field venues with more than 6 runways and fixed stands. The site area is huge, and the roof is usually a transparent semi-closed structure. The stadium space frame structure has good integrity, high rigidity and good seismic performance, and can create a large-span column-free space, which is widely used in small and medium-sized stadium projects. In large-scale stadium projects, it is necessary to form a composite structural system with other types of structures to play their respective advantages. After careful and strict anti-corrosion and fire-proof treatment, the space frame parts are basically maintenance-free within the service life, and the cost performance is very high.
At present, the application of steel structure buildings in high-rise buildings is becoming more and more mature, and it has gradually become the mainstream construction technology, which is the development direction of future buildings.
