The Techno-economic Analysis Of Steel-structured Residential Housing And The Research On The Modernization Of The Housing Industry

As the population urbanism process and development of national economy accelerate, the residential construction of our country lasts to develop unprecedentedly, The requirement of people for resident quality is also high, it promotes the change of the residential construction of our country from extensive production model to intensive model, advances the modernization of the housing industry, improves the quality of residential building. China is one of the largest steel producer in the world with an annual output over one hundred millions tons; our government's policy in changed from the restriction of the use of the steel to positive promotion and development, which guarantees the development of steel structure on material and policy.Steel-structured residential housing is highly industrialized, less wet operation and less pollution, recycled, in good shockproof, it has a slight weight, The construction speed is high, the total cost is lower. It's an ideal residential construction system for modernizing our housing industry.This article explore the application of steel structure and analyze and contrast the techno-economic indicator, through the systematical research on the Steel—structured residential housing structure. According to the characteristic of the Steel-structured residential housing, combined with the actual condition of our country, The article advances an operation model in which the government will provide the policy guidance, enterprise groups will carry out the policy, the industry base of the residential housing will be the carrier and the market-based operation will be the mechanism.This article especially disserts on the protection of the Steel—structured residential housing against fire and decay; explores the steel multi-layer and high residential building in economic aspect ,studies which kind of structure system is suitable for multi-layer and the high residential building separately. The author hope the article can offer certain value for the design and application of the steel structure.At last, the article put forward some extant regrets in steel structure: vacant related regulations; shortage in designer and construction technicians; lack of the suitable related department product.
