Welded steel structure is characterized by high strength, light weight, good overall rigidity and strong resistance to deformation. Therefore, it is particularly suitable for building large-span and ultra-high and super-heavy buildings. The material is homogeneous and isotropic. The body is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, can withstand dynamic load well; construction period is short; its industrialization degree is high, and it can carry out specialized production with high degree of mechanization.
