Study of wind-induced vibration of suspenders for steel truss arch bridges

Herein, reviewing suspender style of steel truss arch bridge, analyzing Reynolds number, Strouhal number, structure vibration factor λl of suspender and the influencing degree of suspender's dynamics characteristic to the suspender vibration, under the engineering background of wind-induced vibration on suspender of one steel truss arch bridge. Also bringing forward the identifying method of suspender vortex-induced resonance relative with factor λl and Reynolds number; and the conclusion from the method is consistent with the fact bridge vortex-induced resonance phenomena. The presenting method can identify the wind-induced vibration on suspender of steel truss arch bridge.
