Talking about the application prospect of steel structure

Steel structure system has comprehensive advantages such as light weight, easy installation, short construction period, good seismic performance, fast investment recovery, and less environmental pollution. The unique advantages of each aspect of development. In recent years, product structure adjustment has occurred in the field of construction engineering in my country. For a long time, the situation that concrete and masonry structures have dominated the world is changing. Steel structures have attracted the attention of the industry due to their own advantages. Quick application.

At present, the general goal of the development of my country's construction industry is: to improve the overall quality of the construction industry, the level of production industry and technical equipment, to achieve strong competitiveness in the international construction market, and to give full play to the construction industry. The role of the leading industry in driving the growth of the national economy and structural adjustment will make the construction industry a veritable pillar industry of the national economy by 2010. To drive the development of related industries in the construction industry, accelerating the development of steel structure engineering is a very important aspect.

The steel structure of high-rise buildings has sprung up like mushrooms in recent years, and it has developed rapidly. The steel structure of 11 high-rise buildings built in my country in the 1980s is 208 meters high, and there are about 32 high-rise buildings under construction or design since the 1990s. The highest steel structure is 420 meters (built) and 460 meters (design). . The steel structure of the 200-meter-high Ocean Building built in Dalian, the design, manufacture, installation and materials are all undertaken and supplied by China, which shows that it is possible to build the highest high-rise steel structure entirely by my country itself.

Large-span space steel structures first let people know about grid engineering, which develops faster and has relatively mature calculations. There are many special grid calculation and drawing programs in China, which are the rapid development of grid engineering. important reason. Reticulated shells have been used in my country. The completed reticulated shell projects are mostly spherical and cylindrical, as well as hyperbolic paraboloids and hyperbolic flat shells. It has many advantages over the grid, especially in the case of very large spans. Suspension and cable-stayed structures, membrane and cable-membrane structures are also widely used in China, mainly used in large-space public buildings such as gymnasiums and stations.

Light steel structure is the fastest growing field in the past decade, and the use of light steel structure in the United States accounts for more than 50% of non-residential construction investment. This kind of structure has a high degree of industrialization and commercialization, fast construction, high comprehensive benefits, and a large market demand, which has caused structural designers to recognize it. The research and development of light steel housing has been piloted in various places, which is an important direction of light steel development. At present, there are various low-rise, multi-storey and high-rise design schemes and examples. Because of its characteristics of large span, large space, flexible use of separation, fast construction speed and favorable earthquake resistance, it will definitely have a great impact on the traditional residential structure model in my country.

Although the steel structure industry has made gratifying progress in my country, the development efforts are far from enough. First, the construction industry of all countries in the world is one of the main users of steel. In the growth period of the construction industry in industrialized countries, the amount of steel used for basic construction generally accounts for more than 30% of the total amount of steel, while my country's current construction steel consumption is only Reach 22% to 26%. The difference between 5% and 6% is mainly due to the relatively small amount of steel used in housing structures in my country. Second, although industry management departments and all walks of life are emphasizing the development of steel structure buildings, because the development of steel structures has been slower than that of reinforced concrete structures for many years, people are not very familiar with it, and they do not know enough about the advantages of steel structures in many aspects. , Some projects can not adopt the steel structure system of the best scheme, and there is a problem of changing the concept. Third, for owners and design units, steel structures are gradually changing the traditional architectural design concept, which requires our structural designers to continuously enrich steel structure design thinking, learn advanced design experience, break conventional structural constraints, and constantly adapt to the requirements of the new situation .

Although there are still various aspects that are not satisfactory or need to be improved, the development potential of steel structures is huge and the prospects are bright. my country's 20 years of reform and opening up and economic development have created a favorable development environment for the application of steel structure systems.

Looking forward to the future, we will make full use of our many years of advantages in innovative Ru0026D, design, and overseas experience in integrated housing to promote more mature steel structure prefabricated products to merchants from all over the world. We are willing to join hands with you in the future and create a better tomorrow!
