Why is steel structure assembly building the best form of green building?
Around 2008, under the impetus of Beijing Olympic Games, a boom of steel structure buildings emerged in China, and the demand for steel structure increased significantly, with a large number of steel structure venues, airports, stations and high-rise buildings coming up one after another. Now, under the advocacy of carbon peak and carbon neutral policy, steel structure building is once again valued, and even regarded as "the best form of green building" by domestic experts.
Reducing the amount of labor and thus shortening the project cycle
Compared with traditional concrete buildings, assembled buildings use significantly less labor for reinforcement tying and formwork support at the construction site, and a large number of prefabricated components are constructed by dry method, which greatly reduces on-site work and greatly improves construction efficiency, resulting in shorter completion time.
Reduce the reliance on manual labor and high degree of mechanization
With the domestic steel structure technical regulations becoming more and more perfect, the design software is available, the size of the components is accurate, etc.; the generality and interchangeability of the steel structure components are strong, which creates extremely favorable conditions for the assembly construction, thus reducing the dependence on manual labor and realizing the mechanization of construction.
Energy saving, green and environmental protection
Firstly, steel structure can significantly reduce carbon emission during the construction process; secondly, most of the construction materials can be recycled and reused when the building is dismantled, as well as the waste generated during the construction process can be significantly reduced, thus reducing the pollution of land and groundwater sources.
Light weight, high strength and good plasticity
Compared with traditional concrete, steel structure is lighter in weight and therefore more suitable for transportation and installation; however, the high strength of steel structure is suitable for large span, high height and heavy load-bearing structure; meanwhile, steel structure has good toughness, high reliability of material and strong seismic resistance, which can resist natural disasters such as earthquakes and typhoons.
Wide range of applications, in line with the requirements of sustainable development
It is not only suitable for residential and commercial buildings, but also for public facilities infrastructure construction, and its plasticity and toughness can be used for high-rise and large-span structures, which has a wider scope of application.
