To study the mechanism on the vortex resonance characteristics of the central-slotted box girders, the large-scale sectional model vibration measurement and pressure measurement are employed. This paper takes a long-span cable-stayed bridge over the Yangtze River as an example to conduct the wind tunnel tests of large-scale sectional model. The test results indicate that it is the inside maintenance rails located in the aerodynamic susceptible sites that cause the vortex-induced vibration (VIV) of bridge model. Accordingly, the inside maintenance rails are proposed to be moved towards the central axis by a certain distance. The static pressure test results show that when shifting the inside maintenance rails, the negative mean pressure at the soffit plate knuckle line will not change dramatically, the fluctuating pressures on the upwind and downwind inclined panels can be reduced, and the fluctuating energy will be dispersed without a consistent predominant frequency. Wind tunnel tests of modified section are conducted and the results show that the VIV of bridge model can be suppressed completely due to the shift of inside rails.
