The Germans took the lead in 1910, put forward the concept of "residential industrialization", nearly 100 years, many countries in Europe, construction of a large number of steel structure, high-rise building, and gradually form a high steel structure industry of production and assembly level. The ratio of the steel structure to the strength of gravity is 3, the ratio of the strength of gravity is 14, so the steel structure is the lightest structure, the structure area is the smallest, and the ductility is good, and the seismic performance is better. China's steel supply is adequate, domestic steel products regardless of quality, price, is still a variety, specifications can meet the needs of steel construction. This production is not only quality assurance, but also the length of the wet homework, in the construction process of environmental pollution. Shorten the construction period, the construction project can be put into use in advance, the loan interest will also be significantly reduced.
Developed countries through nearly a hundred years of development, in the construction of steel structure construction process is introduced in the manufacturing industry production is the whole structure into several modules, after processing plant delivered to the site assembly. Construction steel structure belongs to high technology, high efficiency products, steel structure, effectively promote construction technology improved, promote the construction industry into the class, to a technology intensive industrial transformation, and it also promotes the development of China's iron and steel industry. With the development of the steel structure design level in our country, the development of the industrialization and the quantity of the steel structure building, the economic benefit will be further improved.
Steel structure building comprehensive benefits obvious steel structure building easy to realize industrialized and large-scale production, shorter than the traditional brick concrete structure and reinforced concrete structure construction period, less on-site labor, labor production rate is high, and the quality is easy to guarantee. Compared with reinforced concrete structure, steel structure can shorten the duration of 1/3 or even 1/2. The gains from the use of construction projects in advance are significantly higher than that of the steel structures.
Another advantage of steel structure building is light weight, good ductility and seismic performance is superior, in our country so many earthquake disaster countries, can significantly reduce the losses caused by the earthquake. The steel structure building thermal insulation function is good, is advantageous to the building energy conservation, at the same time the steel can be recycled and used, in accordance with the central "full development of recycling economy, building a conservation oriented society" policy. Steel structure construction speed, high space utilization, interior layout flexibility, the required construction site is small, and other advantages are also very prominent, favored by the developers.
