| 内容記述 | Vortex shedding is a broadly studied phenomenon, in the well-defined conditions of wind tunnel laboratory. But vortex shedding excitation at is not easy to observe in real life on real structures, as its occurrence depends not only on the instantaneous wind speed, but on the duration of the wind event (stability) and the turbulence of the oncoming flow. On large bridges especially, because they are often monitored by complete systems, recording vibrations as well as the wind speed, it is possible to follow multiple occurrences of vortex shedding, when the bridge is prone to it, and analyze the conditions of this occurrence. This was done from the data issued by the monitoring system of The Charilaos Trikoupis bridge between Rion and Antirion, in Greece which showed that the actual wind turbulence was lower than supposed at design stage. The full set of data running from 2005 to 2014 was analyzed with the aim to show the correlation between the vortex shedding excitation and the wind speed stability, the duration of wind events, the wind turbulence at the time of VS excitation and other sources of excitation on the bridge. One of the main feature is to highlight the relationship between the wind conditions and the birth and vanishing of the aeroelastic phenomenon. | |||||||||||
