Why do super high-rise buildings use steel structures?
High strength steel structure, light weight, high rigidity; good homogeneity and isotropy of the material, which is an ideal elastic body, which is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand well Dynamic load; construction period is short; its industrialization degree is high, and it can be specialized production with high mechanization degree.
