Steel is characterized by high strength, light weight, good overall stiffness, and strong resistance to deformation, so it is especially suitable for the construction of large-span and ultra-high and super-heavy buildings; The material has good homogeneity and isotropy, belongs to the ideal elastic body, and best conforms to the basic assumptions of general engineering mechanics; The material has good plasticity and toughness, can have large deformation, and can bear dynamic load well; Short construction period; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization.
High strength steel should be studied in steel structure to greatly improve its yield point strength; In addition, it is necessary to roll new types of steel, such as H-shaped steel (also known as wide flange steel) and T-shaped steel and molded steel plates to meet the needs of large-span structures and super high-rise buildings.
In addition, there is a heat-free bridge light steel structure system, the building itself is not energy-saving, the technology solves the cold and hot bridge problem of the building with clever special connecting parts; The small truss structure makes the cable and water pipe pass through the wall, and the construction and decoration are convenient.
