1. H beam steel steel structure strength is high, compared with I-steel, section modulus is large, in the bearing conditions at the same time, can save metal 10-15%.
2. H-shaped steel in the design characteristics, the style is flexible and rich, in the case of the same beam height, the steel structure of the opening is 50% larger than the concrete structure, so that the building layout is more flexible.
3. from the point of view of the steel structure, the weight of H-beam steel is very light, compared with the weight of the concrete structure, the reduction of the structure's weight, reduces the internal force of the structure design, can make the building structure foundation treatment requirements are low, the construction is simple, and the cost is reduced.
4. H beam in the building stability is high, the hot rolled H-beam based steel structure, its structure is scientific and reasonable, plasticity and flexibility is good, high structural stability, suitable for bearing vibration and impact load of large building structures, strong resistance to natural disasters, especially suitable for some multi-earthquake zone building structures. According to statistics, in the world's devastating earthquake disaster of magnitude 7 or more, the H-shaped steel mainly steel structure buildings have the least degree of damage.
5. increase the effective use area of the structure, compared with the concrete structure, the steel structure column section area is small, which can increase the effective use area of the building, depending on the different forms of the building, can increase the effective use area of 4-6%.
