Field measurement and analysis of wind characteristics and wind-induced vibration responses of Chishi Bridge during construction stages were carried out, where Chishi Bridge is a large-span cable-stayed bridge located in Chenzhou, Hunan, China. The wind characteristic parameters at deck level and pylon top during observation period were analyzed, including the mean wind speeds, wind directions, wind attack angles and turbulence intensities. The wind-induced vibration responses of the bridge were also examined. The results showed that the wind attack angles changed within a rather wide range when the wind blew from the north, while the wind attack angles varied within a narrow range when the wind came from the south. The bridge with double cantilevers during construction stages mainly vibrated in the lateral bending and vertical pendulum modes under strong winds. The measured values of the natural frequencies of the bridge under construction stage agreed well with the analysis results by FEM.
