The real prefabricated building with natural advantages is the steel structure. Prefabricated construction is a “standardized design, factory production, assembly, intelligent information management system of construction, the application” of modern industrial production mode, prefabricated building such as developing the steel structure, can realize the transformation and upgrading of traditional architecture, and can make a lot of migrant workers to become modern industrial workers, but also can guarantee the quality of construction.
Steel structure mainly includes large-span space steel structure, low-rise light steel structure, multi-high-rise and super-high-rise steel structure, etc. Our common sports venues, exhibition centers, airport terminals, etc., all belong to the large-span space structure, including network frame, lattice shell, truss, cable-membrane structure and other structural types. Light industrial plants, warehouses, mobile homes and other low-rise light steel structure; Multi-high-rise and super-high-rise steel structures are mainly used for residential and office buildings.
In China, many landmark buildings are steel structures, such as the national stadium, the national center for the performing arts, the 500-meter aperture spherical radio telescope, Beijing daxing international airport, etc. In foreign countries, many landmark buildings also use steel structure, such as the Eiffel Tower in France, it can be said that these projects incisively and vividly show the advantages of steel structure architecture.
The structural system of steel structure building has steel frame, steel support or steel frame, steel support, steel plate shear wall, etc. At present, in order to reduce the lateral displacement of the building, sometimes buckling constraint support and damper are added.
As we all know, steel structure building has the advantages of high strength, light weight, good seismic performance, fast construction speed, high degree of industrialization, large effective use area, and so on. Compared with other structural systems, steel structure building steel can be recycled and reused.
In addition, if the architectural scheme wants to pursue unique creativity and unique modeling, the structural system must be steel structure, which is one of the important means to show the beautiful architectural landscape. Not only that,building is most suitable for factory production, assembly or welding in the construction site, so that the building melts into a whole, to ensure the integrity of the building structure.
With the encouragement and support of the government for the application of steel structure in construction, the key technical problems of steel structure are constantly overcome,all of which provide a broad space for the development of steel structure. Most importantly, the promotion and application of steel structure has become a social consensus, and steel structure has ushered in the spring of large-scale promotion and application.
