Steel structure over span are increasingly widely used in construction works thanks to their outstanding advantages such as good load-bearing capacity, high aesthetics and fast construction time. With strong development potential, large-span steel structures not only meet current needs but also keep up with modern trends in the future.
1. What is large span steel structure?
Steel structure (SSC) over span is a steel structural system designed to withstand forces with spans exceeding 30m, allowing for large spaces to be created without the need for intermediate support columns. This provides flexibility and space optimization for special projects.
In the context of the increasingly modernized construction industry, large-span KCT has become the priority choice of many investors thanks to its outstanding benefits, meeting technical needs and being an effective and sustainable solution, contributing to promoting the modern construction industry.
2. Characteristics of large span steel structures
Large span KCT brings many outstanding advantages, creating a difference in modern construction works. Below are the outstanding features of this type of structure:
1. Large Open Space
- The distance between columns in a building can exceed 30m, helping to create maximum open space.
- This design is particularly effective in optimizing the usable area, without being hindered by intermediate support columns.
2. Precast Components
- Components are pre-fabricated in the factory with high precision.
- After being transported to the construction site, they are directly installed by crane, helping shorten construction time and improve work performance.
3. Multi-Integration
- Industrialized manufacturing processes allow for the integration of diverse structures right at the factory, ensuring uniformity and high stability for structural frame.
4. Meet Many Design Needs
- Large span steel structures can meet different height and plane design requirements, suitable for many types of buildings such as factories, gymnasiums, airports, etc.
5. Lightweight Material Integration
- Easily combined with non-load-bearing lightweight wall materials, making the construction process faster and more industrialized.
6. High Construction Efficiency
- High precision in component processing, combined with modern crane and assembly process, ensures the construction process takes place fast and safe.
3. Advantages of large span steel structures
3.1 Improve the seismic resistance of the structure
Large span steel structures have good ductility. Under the influence of dynamic loads, it can absorb a lot of energy, thereby reducing the risk of cracking of buildings and significantly improving the seismic resistance of buildings.
3.2 Complies with green building standards requirements
Steel structures can be manufactured in the factory and assembled on site, reducing pollution and complying with green standards. In addition, construction contractors can take advantage of the high strength properties of steel, helping to save on construction materials.
The resource consumption per square meter of large-span steel structures is from 800 to 1000 kg, while the resource consumption per square meter of traditional concrete buildings is more than 1800 kg. Therefore, the construction and manufacturing process of steel structures is 30% more energy-saving than concrete structures.
If dry construction method is adopted, the saving rate of steel structure construction can reach 30% and dust pollution will be reduced by more than 80%. When the steel structure building reaches the end of its service life, the construction waste generated by demolition is 25% less than that of traditional concrete structures. The discarded steel components can also be recycled and reused, the reuse rate can reach more than 90%.

3.3 Reduce labor costs
The construction industry is facing the problem of rising labor costs, which is the main problem limiting the sustainable development of the construction industry. Large-span steel structure industrial buildings can realize industrialized prefabrication, reduce the number of personnel required for on-site construction, reduce the difficulty of allocating human resources, and save construction costs.
3.4 Save time and money
Large-span steel structures are relatively light in weight, so compared with traditional reinforced concrete buildings, their essential costs are more than 30% cheaper, and the transportation costs of all materials are also relatively low. Coupled with the advantages of high strength and relatively small cross-sectional area of the components, the construction area of industrial buildings can be increased by 5% to 8%. Moreover, the construction speed of these buildings is also relatively fast. Compared with reinforced concrete structures, the total construction time is reduced by up to 40%, can be put into use quickly, and reduce capital costs.
4. Conclusion
Above is some general information about the concept, characteristics and some outstanding advantages of large span KCT.
