Time-domain Analysis of Flutter in Long-span Cable-stayed Bridges
Bridge flutter is a forced vibration induced by the turbulent component in the natural atmosphere. It is a limit cycle oscillation that does not cause catastrophic structural failure. However, it occurs frequently, and prolonged vibrations can lead to fatigue damage in structural components. Excessive amplitude or acceleration may cause discomfort to pedestrians, jeopardize high-speed traffic safety, and even result in structural strength failure. In this chapter, flutter analysis is conducted for the Hanjiatuo Yangtze River Bridge on the Yuli Line. Based on the calculation of the structural natural frequencies, a comparison between frequency domain and time domain flutter analysis methods is performed to validate the reliability of the time domain analysis method for the wind-bridge system established in this study.
