Importance of Steel Building in China

At present, the development of building steel industry by the national technical policy support, and more and more clear. Can be expected, with the development of market economy and further mature, China's construction steel structure industry will enter into a rapid development of the times. Building steel structure with light, fast, good, provincial "characteristics, in addition to light with high strength, excellent material properties, production and installation of a high degree of industrialization, should be demolished and better durability and other advantages, but also conducive to saving Resources, reduce carbon emissions, can be recycled, the effective realization of the advantages of green requirements, while restricting the development of China's construction steel structure industry has four major bottlenecks.
First, the steel industry chain. China's steel structure structure of the steel structure of the upstream structure of steel products can not fully meet the needs of the existing market, scientific research is not timely transformation, the design team is weak and more serious problems.
Second, the design theory and team issues. Existing design techniques and methods do not take full advantage of the ductility of steel structures, leading to steel structure "light, high strength, good plasticity" and other advantages can not bring significant economic advantages. "Stupid and heavy" project highlights the field of steel structure and structural design of the overall quality of staff to be improved.
Third, the steel structure of the problem. The whole society on the use of steel structure in the structure of the rationality and necessity of the misunderstanding still exists, resulting in steel structure program is often used in other structural solutions can not solve the project. The market ignored the steel structure "light, fast, good, provincial" features.
Fourth, other potential constraints. For example, steel structure enterprises in the early stage of R & D investment is too large; the existing construction steel structure construction bidding mode, project contracting model, the market price mechanism is not conducive to the steel structure industry application of new technologies and technological innovation practice; To stimulate the development of steel industry and engineering application of effective technology policies.
