An interspaced calculation model of a concrete box-girder with corrugated steel webs was built by sap2000, and the applicability of FEM was proved according to the comparison between the test value and FEM value of concrete box-girder with corrugated steel webs. The influence of structural parameters of corrugated steel webs on dynamic characteristic was analyzed. The results of the research indicates that vibration frequency of box-girder especially torsion vibration frequency can be improved by the augment of corrugated steel webs’ thickness to some extent; vertical and transverse vibration frequency of box-girder is affected less than torsion vibration frequency by the augment of corrugated steel webs’ folded angle; vertical, transverse and torsion vibration frequency increase and then decrease under the change of horizontal face plate width of corrugated steel webs, so the best horizontal face plate width of corrugated steel webs do exist but not too big.
