Wind Oscillation Analysis for Suspension Bridge
This study performed 2D analysis for suspension bridge to predict the bridge superstructure oscillation induced by wind load. Previous studies exhibited that a large torsional mode can be generated by continuous vertical modes in suspension bridge. However, the previous studies did not consider torsional resistance of the superstructure and unrealistic results were shown as wind speeds increasing. Therefore, this study developed a new model considering torsional resistances and predicted responses of a suspension bridge. Analysis results exhibited that vertical oscillations were transformed to the torsional oscillations. With varying torsional resistances, vertical responses were stabilized over a time. However, the rotational response amplified at resonance points. Also, it was found that the resonance of the rotational mode depended on the torsional resistance.
