In this study, in order to accurately calculate the torsional vibration frequency of a simply supported corrugated steel web composite box girder, the element stiffness matrix of the torsional vibration of the simply supported corrugated steel web composite box girder was derived using the principle of constant dynamic potential energy, taking into account the shear deformation of the corrugated steel web. Analyzed the influence of waveform steel web plate type and shear deformation on torsional vibration frequency. The results show that the torsional vibration frequencies of the four commonly used types of simply supported corrugated steel web composite box girders in engineering are relatively close, and the influence of corrugated steel web types on torsional vibration frequencies can be ignored in practical calculations; The influence of shear deformation on the torsional vibration frequency of simply supported corrugated steel web composite box girder is significant, and exceeds the influence on its bending vibration frequency. Therefore, the influence of shear deformation must be considered in practical engineering calculations
