Abstract:The vertical, lateral and torsional vibration of non-streamline suspenders will be generated under wind load acting. To ensure the wind-resistant performance of suspenders of Rongjiang bridge, a three-dimensional whole bridge finite element model and sole suspender finite element model were erected, and than the wind-resistant performance was evaluated. The calculated results present that: The start-oscillation wind speed of vortex induced vibration of some long suspenders is less the corresponding design value. So, some vibration attenuation measures should be taken on the suspenders.
