In order to study the basic mechanical property of cast-in-place stiffening-ribbed-hollow-pipe reinforced concrete
girderless floor, and similarities and differences of the structural performance compared with traditional floor, we carried
out the destructive stage loading test on the short-term load test of floor model with four clamped edges supported in large
scale, and conducted the long-term static load test. Also, the thesis conducted finite element analysis in virtue of ANSYS
software for solid slab floor, stiffening-ribbed-hollow-pipe floor and tubular floor. The experiment indicates that the
developing process of cracks, distribution and failure mode in stiffening-ribbed-hollow-pipe floor are similar to that of solid
girderless floor, and that this kind of floor has higher bearing capacity and better plastic deformation capacity. The finite
element analysis manifests that, compared with solid slab floor, the deadweight of stiffening-ribbed-hollow-pipe floor decreases
on greater level while deformation increases little, and that compared with tubular floor, this floor has higher
rigidity. So stiffening-ribbed-hollow-pipe reinforced concrete girderless floor is particularly suitable for long-span and
large-bay building structure.
