1. Understanding of steel structure: the whole society still misunderstands the rationality and necessity of using steel structure in building structure, which leads to that steel structure scheme is often only used in other projects that cannot be solved
by other structural schemes. The market ignores the characteristics of "light, fast, good and economical" steel structure.
2. Steel structure industry chain: there are serious problems in the configuration of China's construction steel structure industry chain, such as the upstream structural steel products can not fully meet the needs of the existing market, the transformation
of scientific research results is not timely, and the design team is weak.
3. Design theory and team problems: the existing design technology and methods do not make full use of the ductility advantage of Shanxi steel structure, resulting in the
"light weight, high strength, good plasticity" and other advantages of steel structure can not bring obvious economic advantages. The emergence of "stupid and heavy" projects highlights that the overall quality of architectural and structural designers
in the field of steel structure needs to be improved.
4. Other potential constraints: for example, the steel structure enterprise invests too much in the early research and development process; the existing construction bidding mode, project contracting
mode, market price mechanism and other practices are not conducive to the application of new technologies and technological innovation in the steel structure industry; the lack of effective technical policies to effectively stimulate the development of
the steel structure industry and engineering application.
