In this paper, a beam model with intermediate flexible supports under axial force is established by taking the elastic support reaction as a compelling force loading on the beam and by comprehensively taking into consideration the vibration factors of cables such as the axial force, the bending stiffness and the boundary condition of the ends. Based on the model, an analytical algorithm is proposed to calculate the transverse vibration frequency of the cables with intermediate flexible supports. The analytical results are then compared with the test ones under diffe-rent axial forces. It is found that only a small deviation with a maximum of 1.6% is observed, which means that the proposed algorithm is feasible.
