Abstract
This paper reports the results of the dynamic characteristics of a floating type cable stayed bridge (length 292.1m and width 14.9m) and the observation of its dynamic behavior under the typhoon.
Microtremor measurement was performed to determine the dynamic characteristics of the bridge under construction. After the construction of the bridge, the excitation test was carried out in order to confirm its natural frequencies, vibration modes and damping constants, and the dynamic behavior of the girder and cables under the typhoon (maximum wind velocity 27m/s) was observed. From the results of the observation, wind stability of this bridge was confirmed.
