Corrugated steel plate has high shear stiffness and a feature that it resists to in-plane buckling because of its geometric effects. Therefore, the thickness of corrugated steel plate can be smaller compared with the flat plate of the same scale. Using this corrugated steel plate as web of the girder has some advantages that such girder can save the weight of members, improve construction processes and reduce costs. With the development of corrugated web girder, this study shows the girder's basic deformation properties and buckling characteristics through experiments and numerical analysis. Finally, it is suggested in this paper that the girder collapse mode and plastic deformation capacity is evaluable by some valid indicators including buckling strength.
