Vortex shedding occurred at relatively low mean wind velocities between 13m/s and 16m/s in the 2nd Jindo grand bridge. To control the vortex shedding Multiple Tuned Mass Damper(MTMD) was installed in the mid span. The control effects of MTMD was verified by assessing the damping ratio before and after installing MTMD. This paper present the evaluation of damping ratio of a cable- stayed bridge based on measuring data through unified remote monitoring system.
