Technical And Economic Analysis About Steel-structured Residential Housing

In the end of 1990's, with great increasing of steel and iron outPut, our country have provided the sufficient raw material reserve for the structural steel, one kind of new housing construction system-steel structure system housing starts in our country to obtain the more and more widespread value and the development research. Multi-storey and high-rise steel structure residence can alleviate the contradiction between current less urban land for constructing and the area for housing. Moreover, the lighter own weight, which makes its anti-seismic capability stronger, is also ideal structural system; Along with the factorization of member, the mechanization of whole installation in the spot, and the seriation of products matching with.At last industrialization of residential housing will be realized. Mainwhile our govenrmnet'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.This paper explores the application of steel structure and analyse and contrast the technical-economic indicator,through the systematical research on the steel-structured residential housing structure. This paper especially explores the steel multi-layer residential building in economic aspect,and shows the steel structure which has many advantages in technological economy indexes,such as light own weight, good structural property, short construct period,etc. It has obvious comprehensive benefits ,and it is one kind of environmental structure housing deserving to popularize.The purpose of the paper is beneficial to the popularizing and application of the steel structural system which is a real one ,and to promote the developing process of industrialization of residential housing. Meanwhile, The author hopes the article can offer certain value for the design and application of the steel structure.
