Abstract: Based on the consideration of the arch bridge suspender and solving the bending stiffness,moment of inertia,shear deformation and the differential equation of vibration is established,between the frequency and the tension of equation.The frequency equations analysis,put forward to frequency equation numerical calculation method and its practical calculation formula.Through the finite element method and the comparison of the calculation results,Draw suspender tension calculation formula and the suspender conditions selection.Detailed analysis of the influence of suspender tensile test results of main factors,and points out that in the project practice application should pay attention to the problem.
