Technology And Economy Research On Application Of Composite Deck Slab In Steel Structure Buliding

In pace with the development of steel industry and social economics, the Construction Industry worked out " 1996~2000 Architecture Policy" , which is a symbol for the application of steel structure in our country. Steel structure application spreads from industry building to civil building rapidly. It will be an important kind of construction structure.The structure of composite deck slab, as an important component of steel structure building, has been applied for long time , and rich experience is accumulated at abroad. But at home , its application time is short, and experience is lack. It has practical significance the technology and economy research on application of composite deck slab in steel structure building.According to abroad experience, the development course of decking system is from non-structural parts to structural parts. At home, application of decking system is directly enters into the stage of structural parts. In this paper, we study composite deck slab in application technology and economy..There are two problems about practical application of composite deck slab system. One is lacking experience, and theory is in sufficient. The other one is that present price of decking product is high comparing with that of traditional product. It results to construction cost increased directly.Consider above conditions, the research work includes follow respects:(1) General development situation and application prospect of composite deck slab.The characteristics of composite deck slab are constructing rapidly, safety, protecting circumstance, etc. These advantages will be more important in future because of the factors such as social development, technology progress, labor cost rise, etc.(2) Foundation principle and application technology of composite deck slab. Combining practical examples, sum up design method and principle, construction technology and experience of composite deck slab technology. It provides reference for the technology application.(3) Comparison and analysis of decking product series and its technology performance..
