1. Influência das vibrações do cabo na instabilidade aeroelástica de uma viga simples estaiada. / Influence of cable vibrations on the aero-elastic instability of a cable-stayed beam.
This paper is concerned with determining wind critical velocities and post-critical vibration amplitudes in a cable-stayed beam, under wind-rain condition. It is considered the cable sag due to the dead load plus the non-linear coupling between the vibration of both the cable and the beam. Three modes are of special interest, namely the first global mode (be
