Steel structure is a kind of structural form widely used in modern buildings and engineering, its main characteristics are high strength, light weight, fast construction, good earthquake resistance. The high strength of the steel enables the steel structure to withstand large loads, and due to its good plasticity and toughness, it can maintain the stability of the structure under extreme conditions.
In the design of steel structure, the commonly used steel types include carbon steel, alloy steel, etc., and the common specifications are H-shaped steel, I-shaped steel, square pipe, etc. Its intensity parameters are usually characterized by yield strength and tensile strength. The yield strength of commonly used construction steel is generally 235 MPa to 355 MPa, and the tensile strength can reach 400 MPa to 700 MPa.

The application fields of steel structure include high-rise buildings, Bridges, industrial plants, etc. Due to its excellent earthquake resistance, steel structure pays more and more attention in the architectural design of earthquake frequent areas. In addition, the recyclability of the steel structure also makes it advantageous in its sustainable development.
In general, steel structure has become one of the "ultimate" choices of modern engineering construction with its unique performance and adaptability. Under the promotion of technological development and material innovation in the future, its application prospect will be broader.
