First, the steel structure industry chain. There are some serious problems in the construction of steel structure industrial chain in China, such as the steel structure can not meet the needs of the existing market, the transformation of scientific research achievements is not timely, the design team is weak.
Second, design theory and team problems. The existing design techniques and methods do not make full use of the advantages of steel structure, leading to the steel structure of the "light, high strength, good plasticity" and other advantages can not bring significant economic advantages. The emergence of the "stupid and heavy" project highlights the urgent need to improve the overall quality of the building and structural design staff in the field of steel structure. Third, the understanding of steel structure. There is still a great deal of misunderstanding about the rationality and necessity of the steel structure in the whole society, which leads to the fact that the steel structure is often used in other projects. The market ignored the characteristics of the steel structure "light, fast, good, province". Fourth. Other potential constraints. For example, the steel structure enterprises in the early development process of investment is too large; the practice of building steel structure engineering construction in the current bidding mode, engineering contracting mode, market price mechanism is not conducive to the steel structure industry application of new technology and technology innovation; the lack of effective incentive technology policy of steel structure industry development and engineering application etc..
