The positive bending strength of composite girder could be estimated with the ultimate bearing stress of the concrete slab. It is known that the shape of the column make a difference the ultimate bearing stress of the concrete slab. The ultimate bearing stress of the concrete slab isn't influenced by the thickness of flange in case of H-shaped steel column but is done by the thickness of column in case of S.H.S. column. In this report, the experiments of the push-out test of conncrete slab with a S.H.S. column and the subassemblage frame test using the thickness of column as parameter were done, and it is clearly that the thickness of S.H.S. column influence the ultimate bearing stress of the concrete slab and the positive bending strength of composite girder.
