The characteristics of steel are high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for the construction of large-span, ultra-high, and super-heavy buildings; the material has good homogeneity and isotropy, and is ideal elasticity. It is in line with 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; its degree of industrialization is high, and it can be used for specialized production with a high degree of mechanization.
High-strength steel should be studied for steel structures to greatly improve its yield point strength; in addition, new varieties of steel should be rolled, such as H-beam (also known as wide flange steel) and T-shaped steel andPressure plateetc. to meet the needs of large-span structures and super high-rise buildings.
