Steel Structure Systems: Characteristics and Applications
Steel Structure Systems
Steel structures are an indispensable part of modern architecture and are widely used in various construction projects due to their unique strength, flexibility, and adaptability. Steel structure systems include plane load-bearing structures, spatial force structures, and multi-story building structures.

1.Steel structure system: Plane load-bearing structure system
Additional components are composed of longitudinal components and supports, which connect the various plane structures into a whole and bear the longitudinal horizontal force outside the structure’s plane.
The frame steel structure system is a plane load-bearing structure system that has been widely used recently. In addition to factory buildings, there are commercial buildings (such as supermarkets, etc.), car showrooms, gymnasiums, etc.
Steel structure system: Spatial force structure system

(2) Flexible space structures include cable suspension structure, chord support structure, and cable membrane structure
1) Cable suspension structure
The material of the steel cable is a high-strength steel wire strand, rope, or bundle.
Cable suspension structure
The edge member or supporting structure is used to anchor the steel cable and bear the tension of the suspension cable. A ring beam, arch, truss, etc., or a flexible cable can be used as the edge member.
2) Suspension structure

3) Cable-membrane structure
3. Steel Structure system: Multi-story building structure system
The frame steel structure is a commonly used steel structure form, primarily used in large-span public buildings, industrial plants, and some buildings and structures with special requirements for building space, building shape, and building function, such as theaters, shopping malls, gymnasiums, exhibition halls, shipyards, aircraft factories, parking garages, warehouses, industrial workshops, power plant boiler frames, etc.
It has become increasingly widely used in high-rise and super-high-rise buildings. For example, recently, the steel structure frame residential system has become increasingly valued by people.
Frame structures can generally be divided into single-layer single-span, single-layer multi-span, and multi-layer multi-span structures to meet the needs of different building shapes and functions.
According to the structure’s different lateral force resistance systems, the steel structure frame can be divided into a pure frame, a central braced frame, an eccentrically braced frame, and a frame tube.
Which buildings are suitable for steel structures?
1. High-rise building
Steel structures are generally used in workshops suitable for heavy loads and production, such as open-hearth workshops, steel rolling workshops, smelting workshops in metallurgical industrial plants, forging workshops in heavy machinery plants, and hull assembly workshops in shipyards.
2. Light steel structures
3. Bridge structures
4. Large-span steel structures
Using steel structures in large-span buildings can often better reflect and enhance the image of the building itself. For example, the multifunctional gymnasium of the new campus of Guangxi Construction Vocational and Technical College and Guilin North Railway Station, these buildings use steel structures.
