- Abstract:
- Aiming at the parametric vibration problem of cable-stayed cables, combined with engineering examples, four different calculation formulas were used to calculate the fundamental frequency of cables, and through analysis and comparison, it is recommended to use the commonly used fundamental frequency calculation formula considering sag to analyze the parameter resonance of cables. The analysis results show that parametric resonance may occur in the medium and long cable-stayed cables of Huangpu Bridge. The viscous shear type external damper can provide sufficient additional damping for the cable, so that the logarithmic attenuation rate of each controlled mode shape of the cable reaches more than 4.0.
