We all know that when the 2008 Olympic Games, the capital of Beijing that shocked people’s nest?It is a wonder in the history of Chinese architecture, and the bird’s nest is what we call steel structure engineering. It has the following characteristics 　　

 First, it has good seismic resistance. Most of the top of villas with lower floors are sloped, so the roof structure is often made of cold-formed steel products of triangular roof truss type, and then combined with light steel products and gypsum board, the overall formation of a very stable structural system, can be very good earthquake resistance, so generally not.It is often used in earthquake prone areas.

 Second, the weight of steel structure buildings in Hebei Province is only one fifth of that of brick concrete structure, which can withstand the wind of 70m / s and reduce a lot of losses.　　

 Third, this kind of building structure has good durability, which can reduce the impact of steel corrosion, increase the service life of steel products, and make the life of the whole building longer.　　

 Fourth, this kind of building structure also has a good insulation and heat insulation effect.For example, a insulation thermal resistance value of 15 for a 100 mm thick brick wall is basically equal to a 1 m thick brick wall.　　

 Fifthly, an important index to evaluate modern buildings is to see whether its sound insulation effect is good. This kind of building structure also has good sound insulation, and the sound insulation effect can reach 40 dB.　　

 Sixth, this kind of building structure is very healthy, can greatly reduce environmental pollution, basically waste materials can be recycled, meet the requirements of environmental protection, more conducive to health.Seventh, Shanghai steel structure building also has the comfort and fast convenience, can adjust the dry and humidity of the air, but also can be efficient construction without environmental impact.
