Characteristics of steel structures

    Production of steel-based structure, is one of the main building structure types. Steel is characterized by high strength, light weight, stiffness, and therefore for the construction of large-span and super, super-heavy buildings is particularly suitable;

Homogeneous and isotropic material is good, is the ideal elastomer, the most in line with the basic assumptions of the general engineering mechanics; material ductility, toughness, and can have large deformation, can well withstand dynamic loads; construction period is short; industrialization high degree of mechanization can be a high degree of specialization;

Processing of high-precision, high-efficiency, sealed good, it can be used to build tanks, tanks and transformers. The disadvantage is poor fire resistance and corrosion resistance. Mainly for heavy load-bearing skeleton workshop by dynamic loads of the plant structure, plates and shells, tall tower and mast structures, bridges and large span structures such as warehouses, high-rise and high-rise buildings and so on.

Steel should be studied in the future of high-strength steel, greatly improving its yield point strength; addition of new varieties to be rolled steel, such as H-beam (also known as wide-flange beam) and a T-shaped steel and steel sheeting, etc. to accommodate the large span structures and the need to super high-rise buildings.

Steel is divided into light steel and heavy steel. Judge does not have a uniform standard, a lot of experienced designers and project managers are often not fully say it, can be considered and judged with some data.
