The Trough Girder with Corrugated Steel Webs (TGCWs) represents a novel form of through bridge that offers improved stress distribution characteristics and decreased inherent flaws when compared to the traditional trough girder design. Although the static behaviors of TGCWs have been reported before, the dynamic properties of this new structure have been rarely studied, especially under loading. In this paper, the shear lag effect of the bottom flange of TGCWs, and the stiffness correction of CSWs, the analytical equations of natural frequencies and forced vibration were deduced by considering the shear deformation of the TGCWs. The commercial finite element software ABAQUS and multibody system software SIMPACK were integrated to verify the correctness of theoretical values. In comparison to the Chinese design code, the derived analytical equation was more precise. Based on the findings of parameter analysis, it is recommended to construct the TGCWs bridge within a range of 25 m–35 m and to control the velocity of trains at roughly 100 km/h or 150 km/h.
