Hanger cables in suspension bridges are partly constrained by horizontal clamps.
So, existing tension estimation methods based on a single cable model are prone to higher errors as the cable gets shorter, making it more sensitive to flexural rigidity.
Therefore, inverse analysis and system identification methods based on finite element models are suggested recently.
In this paper, the applicability of system identification methods is investigated using the hanger cables of Gwang-An bridge.
The test results show that the inverse analysis and systemic identification methods based on finite element models are more reliable than the existing string theory and linear regression method for calculating the tension in terms of natural frequency errors.
However, the estimation error of tension can be varied according to the accuracy of finite element model in model based methods.
In particular, the boundary conditions affect the results more profoundly when the cable gets shorter.
Therefore, it is important to identify the boundary conditions through experiment if it is possible.
The FE model-based tension estimation method using system identification method can take various boundary conditions into account.
Also, since it is not sensitive to the number of natural frequency inputs, the availability of this system is high.
