Development Status Of Residential Steel Structure Buildings

For a long time, due to the lack of steel in China, the application of building steel structures has been restricted, so that the use of building steel structures has been limited to a very small fan country, and the amount of steel used in construction steel structures accounts for a very low proportion of the total steel output in the country. In 1996, China's steel output exceeded 100 million tons for the first time, in 1998 China's steel output has reached 114.34 million tons, and the annual increase in production is 3 million tons, forming a new situation of steel oversupply, creating an excellent opportunity for the development of China's construction steel structure.

 

 

With the continuous improvement of steel production and the continuous demand for green and environmentally friendly buildings, the application of steel to the main structure of residential buildings is due to the trend of history. China is accelerating the development of steel structure housing industrialization process, the development of standardization, serialization, generalization, specialization, socialization and commercialization of the housing industry modernization system as the basic direction. It is foreseeable that in the near future, there will be a new leap in the development and application of steel structure houses. At present, after extensive domestic research and experimental analysis, the steel structure residential general rest system is used for civil good houses, which has unique advantages, compared with other residential general systems, the main features are:

 

 

1. Light weight, which can reduce the weight of buildings by about 30%- conducive to the construction of high-rise buildings, especially in places with low geological bearing capacity and high seismic intensity, its comprehensive economic benefits are better than the general residential building system.
 

2. Flexible layout, large opening, so that the room type is rich, can increase the building area about 3%, 5%. With full flexibility, modification and security, is conducive to meet the living needs of modern people, adapt to the market demand of modern housing.

 

 

3. Factory production can be easier to achieve industrialized, standardized and mass production, and improve labor productivity.
 

4. The construction period is greatly shortened. According to the research, the construction period of steel structure construction can be shortened by half than that of concrete construction, reduce the amount of wet work, and its energy-saving index can reach 50%, showing the environment-friendly green building system.

 

 

Steel structure housing is suitable for large-scale production in factories, and the degree of industrialization and commercialization is constantly improving, which can integrate design, production, construction and installation. In turn, the level of housing industrialization can be improved. Based on the above advantages, steel structures are bound to have good development prospects in the residential market.
