Analysis of characteristics of H-shaped steel
Analysis of characteristics of H-shaped steel

1. High structural strength: Compared with the I-beam, the section modulus is larger, which can save 10-15% of metal under the same load-bearing conditions.

2. Flexible and rich design styles: When the beam height is the same, the bays of the steel structure can be 50% larger than the bays of the concrete structure, thus making the building layout more flexible.

3. Light weight of the structure: Compared with the weight of the concrete structure, the weight of the structure is reduced, which reduces the internal force of the structure design, which can make the foundation processing requirements of the building structure lower, the construction is simple, and the cost is reduced.

4. High structural stability: The steel structure mainly made of hot-rolled H-shaped steel has a scientific and reasonable structure, good plasticity and flexibility, high structural stability, and is suitable for building structures that can withstand large vibration and impact loads, and can resist natural disasters. Strong, especially suitable for some building structures in earthquake-prone areas. According to statistics, when a devastating earthquake of magnitude 7 or above occurs in the world, steel structure buildings dominated by H-shaped steel suffer the least damage.

5. Increase the effective use area of the structure: Compared with concrete structures, the cross-sectional area of steel structure columns is small, which can increase the effective use area of the building. Depending on the different forms of the building, the effective use area can be increased by 4-6%.

6. Save labor and materials: Compared with welding H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy, and labor, have low residual stress, and have good appearance and surface quality.

7. Ease of machining: easy to connect and install structurally, and easy to dismantle and reuse.

8. Environmental protection: The use of H-shaped steel can effectively protect the environment, which is reflected in three aspects: First, compared with concrete, dry construction can be used, which produces less noise and less dust; second, due to the reduced weight, soil for foundation construction is required The amount is small, causing little damage to land resources. In addition, the amount of concrete is greatly reduced, and the amount of rock excavation is reduced, which is conducive to the protection of the ecological environment; thirdly, after the service life of the building structure expires, the amount of solid waste generated after the structure is dismantled is small, and scrap steel Resource recovery value is high.

9. High degree of industrial production: The steel structure mainly made of hot-rolled H-shaped steel has a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, easy installation, and easy quality assurance. It can be built as a real house production factory and bridge production Factories, industrial plants, manufacturing plants, etc. The development of steel structures has created and promoted the development of hundreds of emerging industries.

10. Fast construction speed: it occupies a small area, is suitable for all-weather construction, and is less affected by climate conditions. The construction speed of steel structures made of hot-rolled H-shaped steel is about 2-3 times that of concrete structures. The capital turnover rate is doubled, which reduces financial costs and thus saves investment.
