Chinese academy of engineering, tongji university professor ShenZuYan in "influence China

The third China steel structure industry peak BBS" analyses China's construction steel structure industry development present situation, and the gap in developed countries, and for promoting China's construction steel structure industry development puts forward some Suggestions.

Construction steel structure industry with huge foreign gap is big also

ShenZuYan pointed out that at present, China's construction steel structure industry has become a huge industry, steel structure only subject of manufacturing output value of more than 60 billion yuan, has been formed in the steel production, steel structure design, component processing and production, components are installed and related industries a industrial chain. Construction steel structure industry development at the same time also contributed to the related industry development.

ShenZuYan said, although our country construction steel structure industry developing rapidly, but compared with the developed countries still has a lot of gap. Mainly displays in the following three aspects: one is the crude steel production the rapid growth and the total amount is very big, but the building steel structure steel amount to total steel output ratio is not high, The second is design standards covering the basic construction steel structure field, but in high performance steel application technology, some new structure system is yet to be perfect, most employees on the building of the application of steel structure applicability and rationality is a misunderstanding; The third is steel structure industry chain is yet to be perfect, and steel structure industry related supporting industry lags behind the development of steel structure industry itself, and steel structure system adapt to the building system development and three big plank industry has just begun, etc. Construction steel structure foreign experience is worth reference

Foreign steel structure production processing pay attention to steel structure system building development, steel structure production processing from design to construction to provide the full service. They from the project bidding stage began to intervene, recommend steel structure system, until finally the construction completion. ShenZuYan think, China's steel structure processing enterprise compared with the developed countries mainly displays in the following three aspects.

First, in the steel products. High performance steel including high strength steel, high seismic performance of steel, high welding performance steel and special thick steel plate and ultrathin steel plate of the material such as production are less, issues such as quality.

Second, in the steel structure processing aspects. Steel structure system of building steel structure processing industry development is rapid development premise, it can make the steel structure processing complete from the design, manufacture, installation and construction to marketing, full service, can make the steel structure building become commodities, batch production, fully embodies the advantages of modern industrial production, reduce costs, increase production, improve comfort and improve the durability. Europe, America, Japan and other developed countries have been combined with its own national conditions developed a variety of steel structure system building and breakthroughs. Our country has just started, catching up with the need.

Third, the steel structure consulting services aspects. Foreign attaches great importance to steel structure consulting services, Europe, America, Japan and other countries (regions) have been set up in steel structure industry consulting services. Our country is also a steel structure industry consulting services, but really have a promotion from steel structure industry development role, has yet to produce.

Construction steel structure industry development the urgency and necessity

At present, the development of construction steel structure industry of the national technology policy support, and more and more clear. It is predicted that with the development of the market economy and further mature, China's construction steel structure industry will enter into a rapid development of The Times. ShenZuYan said, construction steel structure with "light, fast and good, the province", in addition to the characteristics of high strength with light resistance, excellent material performance, fabrication and installation of high degree industrialization, should be removed and good durability advantages outside, still have to save resources, reduce carbon emissions, recycling, the efficient implementation of the "four a environmental protection" green requirements of the superiority. Construction steel structure industry development bottleneck

ShenZuYan that restrict our country building steel structure industry development has four big bottleneck.

First, the steel structure industry chain problem. China's construction steel structure industry chain configuration existing upstream structural steel products cannot be completely satisfied the demand of the market, the scientific research achievements in the design team, is a serious problem.

Second, the steel structure problem of understanding. The whole society to building structure with steel structure rationality and necessity still has a lot of misunderstanding, lead to steel structure scheme is often used in other structure scheme can't solve project. Ignore the market steel structure "light, fast and good, the province" characteristics.

Third, the design theory and team problem. The existing design techniques and methods do not make full use of the advantages of steel structure ductility, resulting in steel structure "light weight, high strength, good plasticity" advantage can't bring obvious economic advantages. "Stupid, heavy" the emergence of the steel structure engineering highlight in the field of architecture and structure design team to improve the overall quality.

Fourth, other potential factors. For example, steel structure enterprise in the process of research and development investment too big, The existing engineering construction bidding mode, project contracting mode, the market price mechanism against steel structure industry new technology application and technology innovation practice; The lack of effective incentive steel structure industry development and engineering application of effective technical policies, etc.

Construction steel structure industry development and a suggestion

For the development of China's construction steel structure industry, ShenZuYan puts forward eight Suggestions.

First, follow the scientific concept of development, the state and local government should vigorously guide in architecture and civil engineering in the steel structure. Focus on propaganda steel structure advantages, and gradually change the market and the owner of the concept, to promote application of steel structure to eliminate thought disorder, establish the correct concept.

Second, the implementation of the powerful technology policy and market policies, state and local government should launch effective incentive measures to improve the enthusiasm of the steel structure. For example, the steel structure building can decrease the tax rate, the steel structure system building developers can get preferential loans and so on.

Third, establish scientific market operation mechanism, the implementation of the "set design, construction and business in one of the general contracting mechanism".

Fourth, we should study and establish the reasonable engineering bidding mechanism, pay attention to major steel structure engineering on industry technology BangYangXing, demonstration and leading. The irrational structure system, the unreasonable energy consumption of building, reasonable investment regulations should carry out a ticket veto.

Fifth, state and local government should increase in steel structure field research and development investment, cooperation go way, and to form the scientific theory research, technical development and achievements transformation mechanism. The system should be inspired in iron and steel enterprise high performance structural steel and development and application of technology enthusiasm, ensure the new type of popularization and application.

Sixth, the national and local relevant industry associations, registered teacher test center should be joint institutions of higher learning to civil engineering technical personnel steel structure engineering design, production and construction aspects of continue to education, comprehensive training and improve the steel structure basic principle, design theory and production of construction technology level.

Seventh, reform the industry association operation mechanism, give full play to the industry association in the industry development direction of market and technology guidance. Industry association shall organize generic technology research, help steel structure enterprise in market economy development adjustment, give full play to the bridge and link between.

Eighth, in institutions of higher learning in the teaching of civil engineering specialty should improve the steel structure in the course of specific gravity, at least with concrete structure and for future civil engineering professional and technical personnel to lay a solid foundation.
