With using of plain steel plate and internal hollow model, the composite slabs have lots of advantage such as light-weight, sound-proofed and constructing easily for without bottom forms, therefore, this type of composite slabs have very wildly prospect for engineering application. Experiments of six specimens of such composite slabs were conducted to study the mechanical behaviors. Based on the experimental results, the influences of the nominal shear-span of the slabs were studied. During the experimental process, the failure modes, the steel plate and concrete strains development, types of cracking, interface slippage and bend and shear bearing capacity of the decks were focused. Based on the results of the experimental study, the calculation methods for the bend-bearing capacity, the flexural rigidity and the shear-bearing capacity of the composite decks were proposed. The result of the proposed calculation methods agreeed quite well with experimental result. The research results of the article provide experiment and theory basis and reference for actual project application of this new type of composite slab.
