Based on the experiment results, the influence of shear-span ratio and the studs' layout of the composite beams were specifically focused on. During the experimental study, the failure modes, strain developing of concrete and steel shape as well as profiled steel sheeting, the cracks type, the slippage of interface between the steel shape and composite slab, and the failure modes of the composite beams were all stud in detail. The bending bearing capacity and vertical shearing capacity of the eight composite beams were focused on and furthermore the calculation formulas of the bearing capacity of the steel-light weight concrete composite beams with re-entrant trough profiled steel sheeting were presented. Based on the experimental results, it was denoted that all the composite beams were failed in shear-bending failure mode, which was initiated by the shear failure of the composite slabs. Although the composite extent of the composite beam specimens were smaller than the required composite extent from the design code, there were not obvious slip on the interface until the load up to 80 percent of maximum load which also means the plain-section assumption were tenable before the load up to 80 percent maximum load, and the composite beam specimens showed good mechanical behior including high bearing capacity and good ductility, therefore the partialcomposite beam could be adopted and designed. Furthermore, the vibration characteristic including the vibration frequencies and damping ratios of the eight composite beams were also tested in the experiment, and the tested result showed that the damping of the composite beam specimens were smaller.压型钢板挠度计算，按均布荷载值进行挠度计算：舟山市S-373彩钢板压型钢板S-373彩钢板压型钢板舟山市
