- Abstract:

Hong Kong Ting Kowloon Bridge is a three-tower, four-cable-stayed bridge with novel structure. In order to carry out more accurate wind and seismic analysis, as well as future bridge health testing, experimental measurement of the self-vibration characteristics of bridges is essential. According to the acceleration sensor data of the vibration of the bridge under the environmental excitation (mainly wind) of the Tingjiu Bridge, the mode shape and corresponding natural frequency were determined by spectral analysis method, and the damping ratio was measured by the half-power bandwidth method. The mode shape and corresponding natural frequency are basically consistent with the finite element analysis results.
