The Static Analysis Of Comby Corn Reinforced Concrete Hollow Slab

In all kinds of light floor system which can span a long distance, comby corn reinforced concrete hollow slab is a newly developed system. This kind of floor system can provide flexible spaces economically, and can be used widely although the design theories are not mature.This kind of floor system belongs to the hollow reinforced concrete in which a number of prefabricated permanent high strength thin-wall core boxes are laid. This paper focuses on the analysis of the slab under static forces, and the result of the research will supply some advices on the designing of the floor system.Firstly, the elastic solution of the slab on the simple support is given using simulating sandwich plate method. And then the software-ANSYS is used to discover the behavior of the rib and the boards on the simple support and the fixed support. At the same time, analysis is also done to the spaced rib slab which is in the same condition to compare with the former one. At last, the effect of height and width of the rib are discussed.The result showed that the comby corn reinforced concrete hollow slab has good load carrying capability. Both in simple and fix support, in comparing with the spaced rib slab, the stress in the comby corn hollow slab is much smaller. Both the up and low boards play an important action in carrying the load, so more attentions must be paid in board when designing it. The comby corn reinforced concrete hollow slab is much rigid than the spaced rib slab, therefore the displacement is much smaller. This made it adapt in the large span structures. Enlarging the rid height can decrease the stress and displacement in the slab evidently. But increasing the rid width can do almost nothing to the improvement the slab capability.
