Abstract:

Cable is the key component of cable-stayed bridge. The rustiness and the damage of cables inevitably cause the change of cable force, girder alignment and the status of the structure. As a result, it threatens the security of bridge. In present paper, latest methods to monitor cable force and girder deflection are introduced. By means of sensitivity analysis, a cable damage identification method based on the deflection and cable force monitoring is addressed and applied to the analysis of a single tower cable-stayed bridge.
