The test of external tendons＇ force in cablestayed has been applied, but how to measure accurately small and medium- sized component external tendons＇ force at present is not settled yet. This article gives practical calculation formulas between the force of external tendons and frequency through theoretical derivation, and verifies the practical calculation formulas through experimental data and finite element analysis. The results showed that the calculation formulas can be used to test the force of external tendons in small and medium -sized component, the error meet the actual needs of the project.
