Full Article:

This paper proposes a new frequency method applied to calculate cable force for cables with the intermediate multi-support from measured natural frequencies. The proposed method has established new relationship between cable frequency and tension force, taking cable force, the intermediate multi-support, flexural rigidity, boundary conditions of two ends into account. Following the classical guidelines of cable dynamics, and by making some simplifications, frequency equation has been obtained in non-dimensional form. When natural frequencies have measured, cable force can be calculated by solving frequency equation. Comparison with Matharmethod and the proposed method in the field test, the difference of cable force result between two methods is just only 1%, so the proposed method has been made to validate.
