INFLUENCE ANALYSIS OF NATURAL VIBRATION CHARACTERISTICS OF STEEL BOX GIRDER WITH SINGLE CABLE PLANE AND LARGE CANTILEVERS.

In order to study the effect of cable damage on the self-vibration characteristics of steel box girder cable-stayed bridges with a single-cable plane and large cantilevers, a finite element model of the bridge was elaborated using the finite element software Midas/Civil to find out self-vibration characteristics of the cable-stayed bridge. The self-vibration characteristics of the bridge were also analysed for different damages to the cables and for different degrees of the damages to the cables. The structural health of a bridge can be diagnosed and assessed based on self-vibration characteristics of the studied structure. [ABSTRACT FROM AUTHOR]
