[0002] The characteristics of steel are high strength, light weight, good overall rigidity and strong deformation ability, so it is particularly suitable for building large-span, super-high and super-heavy buildings; the material has good homogeneity and isotropy, and is an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have large deformation, and can withstand dynamic loads well; the construction period is short; it has a high degree of industrialization and can carry out specialized production with a high degree of mechanization. Steel frame structures should study high-strength steel to greatly improve their yield point strength; in addition, new types of steel should be rolled, such as H-shaped steel (also known as wide flange steel) and T-shaped steel and corrugated steel plates to meet the needs of large-span structures and super-high-rise buildings.
