First, the characteristics of steel are high strength, light weight and high rigidity, so it is especially suitable for building large-span and super-high and super-heavy buildings;
Second, the material structure of the steel structure is good in homogeneity and isotropy. It is an ideal elastomer, which is in line with the basic assumptions of general engineering mechanics. It is an ideal building material for today.
Third, its material has good plasticity and toughness, and it can have large deformation, so it can withstand the dynamic load well. Many large buildings are mainly steel structures. The first door in the world today is located in Suzhou, which is dominated by steel structures.
Fourth, the construction period is short. A building of 300 square meters can be completed in just one month from construction to renovation in just five people and 30 working days. It can save money, save time, and save labor!
Fifth, the degree of industrialization of steel structure buildings is high, and the degree of mechanization is high, which can carry out specialized production, improve work efficiency, and reduce construction difficulty. It is in line with the current high-speed and energy-saving society.
Sixth, the disadvantage is poor fire resistance and corrosion resistance.
The steel structure is mainly used for load-bearing skeletons of heavy-duty workshops, plant structures subjected to dynamic loads, plate and shell structures, towering TV towers and mast structures, bridges and warehouses, and other large-span structures, high-rise buildings and super high-rise buildings.
