V ALIDATION AND TEST

Validation n this research, the proposed method is applied and validated by Choi's data [4], which were collected from the Hwamung bridge, Korea. The cable properties and geometry for BLC02 cable of the Hwamung bridge are shown in Tab. 1, the first six frequencies are shown in Tab. 2, and Tab. 3 will show the comparison of other methods with this study's method.
