Fabricated steel structure buildings are not a new thing, especially in the recent years when the national policy level has seen frequent warm wind, and relevant policies have been implemented in various regions. But it is undeniable that the current situation seems to be very different. On the one hand, fabricated steel structure buildings are widely used in public buildings with high acceptance. On the other hand, prefabricated steel structure buildings are rarely used in the residential area with huge market, and it is difficult to move forward. From the perspective of technology and economy, what is the problem? Here is a brief summary and analysis.
Building system integration
The past years’ experience shows that the mode dominated by steel structure engineers is unfavorable to the promotion of fabricated steel structure buildings. This problem is not prominent in individual design of steel structure public buildings, but it is very important in prefabricated steel structure residential buildings.
The construction of prefabricated steel structure residence is a process of building system integration to realize the overall building functions and meet the needs of users. More and more enterprises have shifted their focus to the idea of building system integration and building productization led by the architecture specialty. In other words, this is a product development led by the product manager. Any problem that affects the product function may cause the product to fail to satisfy customers.
Therefore, the traditional practice of directly replacing concrete structures with steel structures must be abandoned. From the perspective of system projects, the use function and living quality of steel structure residential buildings must be improved as a whole, with building functions as the core, structural layout as the basis, and industrial enclosure and interior decoration as the support. It is necessary to comprehensively consider the building function, structure, enclosure, interior decoration, electromechanical, and realize the coordination and integration of house type, facade, structural system, enclosure system, pipeline system, fire prevention, interior decoration and other aspects, and finally realize “building a house like a car”.
Whether the cost is too high
High cost is the key factor that hinders the development of fabricated steel structure buildings, especially residential buildings. Compared with traditional reinforced concrete structures, the cost of steel structures is significantly higher. This seems to be a deep-rooted impression.
In fact, in recent years, with the sharp reduction of steel prices and the gradual maturity and competition of the supporting parts industry, the cost of prefabricated steel structure residential buildings has been basically close to that of traditional concrete shear walls. The shorter construction period, better quality and higher assembly rate make it easier to obtain policy support that has been gradually implemented in various regions.
From the above review and analysis, it can be basically judged that the policy guidance, cost and technology of prefabricated steel structure buildings have presented a favorable trend, and fabricated steel structure buildings have reached a turning point of vigorous development.
