Why Steel Structure Buildings Are Becoming More And More Popular
Feb 11, 2022
People choose new building materials, which show that traditional building models are not suitable for all customer groups.
Compared with traditional materials, steel structures have the following characteristics:
1. High strength and lightweight
Although the density of steel is higher than that of other building materials, its strength is very high. Under the same stress, the steel structure has a small dead weight and can be made into a structure with a larger span.
2. Good plasticity and toughness
The plasticity of steel is good, and the structure will not break suddenly due to accidental overload or partial overload under normal circumstances. The toughness of steel makes the structure more adaptable to dynamic loads.
3. Reliability
The internal structure of the steel is uniform and isotropic. The actual working performance of the steel structure is in good agreement with the theoretical calculation results used, so the reliability of the structure is high.
4. Can be welding
Due to the weldability of steel, the connection of steel structures is greatly simplified, and it is suitable for manufacturing various complex-shaped structures.
5. High degree of industrialization in steel structure production and installation
The production of steel structures is mainly carried out in specialized metal structure factories, so the production is simple and accurate. The finished components are transported to the site for installation, with a high degree of assembly, fast installation speed and short construction period.
6. Tightness
The internal structure of the steel is very dense, and when it is connected by welding, even when connected by rivets or bolts, it is easy to achieve tightness and no leakage.
7. Fire resistance
When the surface temperature of the steel is within 150°C, the strength of the steel changes little, so the steel structure is suitable for hot workshops. When the temperature exceeds 150 ℃, its strength decreases significantly. When the temperature reaches 500-600t, the intensity is almost zero. Therefore, in the event of a fire, the steel structure has a shorter fire resistance time and sudden collapse will occur. For steel structures with special requirements. To take heat insulation and fire resistance measures.
8. Corrosion resistance
Steel is prone to rust in a humid environment, especially in an environment with corrosive media, and requires regular maintenance, which increases maintenance costs.
