Sažetak
The paper describes the modifications of bridge aeroelastic behaviour due to stationary vehicles on the deck. Aerodynamic force coefficients, as well as aeroelastic flutter derivatives, obtained by the free-vibration technique, are analyzed for the Kao-Pin Hsi Bridge in Taiwan. When considering static response, vehicles are observed to change aerodynamic coefficients of the bridge, especially in case of torsional coefficient. When considering one degree of freedom motion of the bridge-deck section, empty bridge without the vehicles proved to be more prone to torsional flutter than bridge with various arrangements of the vehicles. For two degrees of freedom system, non-moving vehicles are observed to have an adverse effect on the bridge stability. This is particularly exhibited in the experiment with the vehicles placed in the leeward traffic lanes of the bridge. At last, galloping sensitivity is not much influenced by the presence of vehicles.
