| Abstract: | Modal test was done on a cable-stayed structure in its healthy and two damaged conditions. Curvature of the Frequency Response Function (FRF) was used to detect the location of damage. Results show that cur vature of the FRF is very sensitive to the damage and can be used as an excellen t indicator. |
