Experimental Study Of The Performance-based Design Of Composite Slab

With the acceleration of the urbanization process in China, the entire construction industry is facing residential demand, increasingly expensive labor costs, construction quality needs to be improved as well as the extensive mode of production an urgent need to change this reality. Thus traditional residential construction serious constraints and influence the development of the residential construction and cannot meet the needs of the current residential construction. Therefore, changing the way of residential construction, and vigorously promote the industrialization of residential construction, to realize that the housing industry is very adapt to the needs of the development of China’s urbanization process. At the same time, housing industry fully reflect a country’s social, economic and scientific development level of the mirror. With the strong development of the housing industry and the analysis of the new residential structure, designing an excellent structural performance, easy to use, reasonable cost, while the new composite structure for energy conservation and environmental protection, and thus to improve the technological level of China’s building and promoting the rapid economic growth and achieve energy saving and environmental protection has important practical significance. The floor is concerned, the proportion of the floor structure in the whole building is the largest and most widely used. Therefore, the research and development of the laminated floor has great economic and social benefits. There are various forms of overlapping slabs, and this research is the China17Metallurgical Group Corporation in cooperation with Anhui Jianzhu University designed a new type of performance-based design of reinforced concrete composite slab.Firstly, This paper introduces the research background of a new reinforced concrete Composite Slab elaborate such new Composite Slab Construction and technical characteristics. That such a laminated board has excellent structure design, convenient construction and energy saving and environmental protection. Then through the static load test comparison of three o laminated boards, resulting in the specimen plate cracking load, ultimate load, load-deflection relationship and the load-strain relations and other performance data. From research and analyze each specimen plates under monotonic static loading force the destruction characteristics and patchwork structural measures rationality. Finally, through the use of ANSYS finite element program on the three specimens board established a finite element analysis model and nonlinear analysis. Finite element analysis and experimental results were analyzed to draw some useful conclusions computer simulation to provide a reference for the future of this new laminated floor.
