Steel structure refers to a structural system that uses steel as the main building material. It has the following characteristics and performance:
1. High strength: Steel is an excellent structural material with high tensile and compressive strength, making steel structures have excellent wind resistance, seismic resistance, and load-bearing capacity.
2. Good rigidity: Steel structures have high rigidity under stress, can maintain good shape, are not prone to deformation and displacement, and ensure the stability of the structure.
3. Short construction period: Due to the use of factory prefabrication and on-site installation for steel structures, the construction period is relatively short, which can reduce the construction period and improve the project progress.
4. Lightweight: Compared to traditional concrete structures, steel structures have a lighter self weight, which can reduce the pressure on the foundation and foundation, and lower the soil requirements of the building.
5. Good corrosion resistance: Steel structures have good corrosion resistance, especially with appropriate coatings or anti-corrosion treatments, which can prevent steel from oxidation, corrosion, and rusting.
6. Detachable and Reusable: The components of steel structures can be disassembled and reused, which is beneficial for resource conservation and reducing environmental impact.
7. Good aesthetics: Steel structures can create buildings with unique aesthetics by designing diverse forms and appearances.
However, there are also some challenges and precautions in steel structures, such as the need for fire isolation, anti-corrosion treatment, sound insulation, earthquake resistance and other engineering measures, as well as high precision requirements for welding, connections, and components. In design and construction, it is necessary to comprehensively consider and reasonably apply specific requirements and conditions.
