Aimed at open/close atmospheric boundary layer wind tunnel in Shijiazhuang Tiedao University, a new testing set-up of rain-wind induced vibration of stay cables was designed. Every component of the testing set-up and its working principle were presented. A series of rain-wind induced vibration tests were performed using this set-up. The effects of testing parameters, such as rainfall intensity, inclination angle of cable, wind yaw angle and so on, on rain-wind induced vibration of stay cables were analized. The testing results show that the set up can well meet wind tunnel test research demand on rain-wind induced vibration of stay cables. For cable model with diameter of 155mm in this research, under the parameters composing of inclination angle 25°, wind yaw angle 35°, rainfall intensity 10mm/h and wind velocity 13m/s, cable vibration gets the largest amplitude.
