Analysis of H-beam characteristics

Analysis of the Characteristics of American Standard H-shaped Steel H-shaped Steel

◆ High structural strength: Compared with I-beam, it has a larger cross-sectional modulus and can save 10-15% of metal under the same bearing conditions.

◆ Flexible and rich design style: With the same beam height, the bay of steel structure can be 50% larger than that of concrete structure, making the building layout more flexible.

◆ Light self weight of structure: Compared with the self weight of concrete structures, the reduction of the self weight of the structure reduces the internal force of the structural design, which can lower the requirements for foundation treatment of building structures, facilitate construction, and reduce costs.

◆ High structural stability: Steel structures mainly made of hot-rolled H-beams have a scientific and reasonable structure, good plasticity and flexibility, and high structural stability. They are suitable for building structures that withstand large vibration and impact loads, and have strong resistance to natural disasters, especially suitable for building structures in earthquake prone zones. According to statistics, in the world's devastating earthquake disasters of magnitude 7 or above, steel structures mainly made of H-beams are less affected.

◆ Increase the effective usable area of the structure: Compared with concrete structures, steel structure columns have a smaller cross-sectional area, which can increase the effective usable area of the building. Depending on the different forms of the building, it can increase the effective usable area by 4-6%.

◆ Labor and material saving: Compared with welding H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy, and labor, reduce residual stress, and have good appearance and surface quality

◆ Easy for mechanical processing: easy to connect and install the structure, as well as easy to remove and reuse

◆ Environmental protection: The use of H-shaped steel can effectively protect the environment, which is manifested in three aspects: firstly, compared to concrete, dry construction can be used, resulting in less noise and dust; Secondly, due to the reduction of self weight, the amount of soil taken for foundation construction is small, which causes little damage to land resources. In addition, a significant reduction in concrete usage and the amount of rock excavation is beneficial for 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 the recycling value of scrap steel resources is high.

High degree of industrial production: Steel structures mainly made of hot-rolled H-beams have a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, easy installation, and easy to ensure quality. They can be built into real house production factories, bridge production factories, industrial factory building production factories, etc. The development of steel structures has created and driven the development of hundreds of emerging industries.

◆ Fast construction speed: small footprint, suitable for all weather construction, and less affected by climate conditions. The construction speed of steel structures made of hot-rolled H-beams is about 2-3 times that of concrete structures, and the capital turnover rate is doubled, reducing financial costs and saving investment.
