Study On The Residential Design For The Large-span Concrete Slab With Low Ribs

The large-span slab with low ribs behaves as a dimensional object under load. It has some characters such as less self-gravity and using less material and receive higher building load comparing with the ordinary concrete floor, Moreover, It require lower technique and it's more convenient to construct. All advantage mentioned above indicate the large-span slab with low ribs is a perfect floor system which suits for the adaptability house structure. In order to promote The large-span slab with low ribs application in the project of the residence building, this paper has studied from the theory of the residence building and its corresponding structure system with the structural point of view, made the discussion for the rational residential design by the large-span slab with low ribs, some work has been done for its application by the capability of technological and economic analyzed under the whole residential structure system and demonstration design.This paper has begun with researching of the residential theory. And then introduced the demand background and the development of the adaptability house. It have summarized the characteristic of the adaptability house design at present and given some opinions about the requisition of structure for the adaptability house .Then the adaptability house structure design is analyzed especially, through the analysis of many kinds of instances, the using of large-span slab with low ribs in the adaptability house structure is explained and the characteristic of its engineering design is summarized.Being technological and economy is a key factor whether a kind of structure can be used widely. The paper does the best to overcome the one-sidedness to its analysis in the past and analyses in an all-round way with a kind of more scientific method. Through analyzing wholly, the quality of technological and economy in different size of the large-span slab with low ribs with concrete slab has been compared. A kind of objective appraisal on its composite index has been made, and a method for the effective choices of various kinds of floor systems has been offered.Finally, the paper has introduced the calculation method of The large-span slab with low ribs in projects, consulted the research results of our team, the calculation method of finite element for engineering design is chosen. It has selected examples of a project and done a detailed design to which is chosen, including floor size option, load and internal force calculating, reinforced calculating and construct measures, as an result to offer reference to project designer.
