Steel structure characteristics



The main structure of the steel structure is one of the main building structures. Steel is characterized by high strength, light weight, stiffness, it is used to build large span and high, super heavy buildings are particularly suitable;

Material is homogeneous and isotropic, is the ideal elastomer, the most suitable for general engineering mechanics of the basic assumptions; plastic material, good toughness, may have a large deformation, can withstand the dynamic load; construction period is short; its industrialization High degree of high, high degree of efficiency, good sealing, it can be used to build gas cylinders, oil tanks and transformers and so on.

The disadvantage is poor fire resistance and corrosion resistance. Mainly used for heavy-duty workshop load-bearing skeleton, by the dynamic load of the plant structure, plate and shell structure, towering TV towers and mast structure, bridges and warehouses and other large-span structure, high-rise and high-rise buildings.

Steel structure in the future should study high-strength steel, greatly improve its yield point strength; in addition to rolling new varieties of steel, such as H-beam (also known as wide flange steel) and T-shaped steel and steel plate to adapt to large span structure And the need for high-rise buildings.

Steel is divided into light steel and heavy steel. Judgment does not have a unified standard, many experienced designers or project managers are often unable to fully understand, you can take some data into account and to judge.
