INVESTIGATION OF THE VIBRATIONAL BEHAVIOR OF A CABLE-STAYED BRIDGE UNDER WIND LOADS
Wind tunnel tests were carried out on a two dimensional model to establish the flutter stability of the bridge and to determine resonance vibrations due to vortex shedding. During construction of the actual bridge, vibration measurements were performed and the wind-induced vibrational behavior of the structure was observed. Measured resonance vibration agreed very well with the values for the model tests in the tunnel.
