With the continuous promotion of energy conservation and emission reduction in China, steel structures as recyclable low carbon green building materials have become the focus of attention of the construction industry.
Prospect of steel structure building in China
With the continuous improvement of human cultural life, the requirements for high-rise and long-span buildings are getting higher and higher, and steel buildings with their own advantages will account for more and more of China's engineering construction. With the policy of expanding domestic demand, the implementation of the western development strategy and the acceleration of urbanization, these will provide a broad market space and development opportunities for domestic steel structure buildings.
Advantages of steel structures
Steel structures have advantages in many ways compared to other construction and can be moved at any time. The specific performance is:
First, due to the good ductility of the steel structure, the plastic deformation capacity is strong. With excellent seismic and wind resistance, it can give full play to its role in residential buildings, which will greatly improve the safety and reliability of residential buildings. Especially in the case of earthquakes and other disasters, steel structures can avoid collapse of buildings.
Second, the steel structure of the residential system is lightweight, about half of the concrete structure, which can reduce the cost of the foundation.
Third, the energy saving effect is good, the wall adopts light energy saving standardized square steel, C-shaped steel, sandwich panel, good insulation performance, good earthquake resistance, energy saving.
Fourth，steel structure buildings have the characteristics of green environmental protection. Steel structure residential construction does not need sand, stone, cement, etc., that greatly reducing the amount of sand, stone, ash. The materials used are basically green, recyclable or degradable materials.
Fifth, construction period is at least one-third shorter than the traditional residential system.
Sixth, steel structure residential than the space of traditional buildings is more fully utilized, by reducing the cross-sectional area of the column and using lightweight wall panels, which significantly improve the area utilization rate, so that the effective use of indoor area.
Seventh, it meet the requirements of residential industrialization and sustainable development. Steel structure buildings are suitable for mass production, which have high degree of industrialization, and can save energy.
With the continuous promotion of energy conservation and emission reduction in China, steel structures as recyclable low carbon green building materials have become the focus of attention of the construction industry. It is precisely because of this that China has thousands of steel structure enterprises, steel structure processing volume of tens of millions of tons.
The overall goal of the development of China's construction industry is to improve the overall quality of the construction industry, production industry and technical equipment level, achieve strong competitiveness in the international construction market. Recently in the field of construction engineering in China has appeared product restructuring, long-term condense and masonry structure is changing, steel structure with its own advantages caused concern in the industry, has been reasonable and rapid application.
Although the steel structure industry in China has made welcome progress, but the development of the strength is far from enough. Therefore, our country steel structure construction must continue to develop.
