In order to research that how the degree of shear connection influence the static properties of composite beams such as the relative slip on the interface、bearing capacity and failure mode, four prestressed composite beams with different the degree of shear connection were designed, and were loaded on the two symmetric position. The paper described and analyzed the bending behaviors of prestressed composite beam such as the strain distribution of sections、interface slip、deformation and failure patterns on the base of the experimental results. In addition, the paper revised the calculating formulas of the ultimate bending capacity of composite beams with partial shear connection in Eurocode 4 with the least square method combined with test results of domestic and overseas about seven composite beams. The results showed that the correction values were corresponding well with experimental data and the engineering accuracy.
