摘要：In order to study the effect of interface slip and shear deformation on the natural vibration of composite box girders with corrugated webs (CBBCW), based on the Hamilton principle, the effects of the slip, shear deformation and moment of inertia of CBBCW have been investigated. Further, the flexural vibration differential equations and natural boundary conditions of the CBBCW have been deduced. The formula for the flexural natural vibration frequency of CBBCW has been developed. The influencing rule of the interface slip stiffness and web shear deformation on the flexural natural vibration frequency of the CBBCW has been analyzed. The results of this study show that the analytical results are in good agreement with the results of the ANSYS finite element calculation, and some significant conclusions can be applied to the engineering design. The interface slip stiffness has some effect on the flexural natural vibration frequency of the CBBCW, and the maximum interface slip effect is up to 13.7%. The shear deformation has a significant effect on the natural vibration properties of the CBBCW, and the shear deformation effect increases significantly with the increase of the order of flexural natural vibration frequency. The formula has been developed further as compared with the earlier developed calculation theory for the flexural natural vibration of CBBCW. It can also provide a reference for future study of dynamic characteristics of CBBCW.
