steel structure

Steel structures mainly refer to spatial structures composed of steel plates, sections, and structural components. They boast advantages such as light self-weight, high strength, short construction period, low construction pollution, excellent seismic performance, and recyclability. Common structural types include H-shaped sections, box sections, pipe columns, trusses, catwalk stairs, and special-shaped components, which are widely used in the construction of stadiums and gymnasiums, convention and exhibition centers, bridges, railway station buildings, aircraft hangars, residential buildings, industrial plants, and other projects.

The technical requirements for steel structures involve multiple aspects including design, materials, fabrication, installation, and acceptance, which must strictly comply with international standards and industry standards. Taking American-standard (e.g., AISC, ASTM) steel structural components as an example, the main technical parameters cover material properties, section characteristics, connection design, and tolerance requirements, etc. The following is a classified explanation of the core parameters
