Abstract

Gongan Changjiang combined highway and railway bridge is a steel truss beam cable-stayed bridge, which main span is 518m, In this paper, the behavior of the bridge under wind is systematically studied by analysis or by wind-tunnel model test. The wind characters at bridge location are analyzed. The vibration characters of the bridge are calculated. The static aerodynamic coefficients of the main girder were measured, the flutter stability and the vortex-induced vibration performance were studied by the sectional model wind tunnel test. The aero-elastic model wind tunnel test for the completion state and the construction stage of the bridge are carried out. It is shown. the Aerodynamic stability of the main girder is satisfied. The amplitude of vortex-induced vibration and the buffeting responses are all meet the need of the national code
