It is particularly suitable for buildings; the material has good homogeneity and isotropy, is an ideal elastomer, and is most in line with the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can undergo large deformation, and can withstand dynamic loads well. The construction period is short. In the future, steel structures should study high-strength steel to greatly increase its 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 profiled steel plates to adapt to large spans. To meet the needs of structures and super high-rise buildings, steel structure connection methods generally include welding, riveting, and bolt connections. For steel structures that use bolt connections, drilling devices need to be used to drill holes at corresponding positions during the production process to facilitate their installation.
