Abstract In order to suppress wind-induced vibration response of a high-rise building structure, a flow control method based on passive suction and blowing was proposed.The square cross-section high-rise building structure was combined with passive suction and blowing rings.A suction and blowing channel was set on the facade of the structure, and the unsteady vortex shedding was destroyed by the structure wake blowing to reduce average wind load and fluctuating wind load acting on the structure surface, and suppress wind-induced vibration.In wind tunnel tests, variation laws of wind load, wind-induced vibration response and tail flow field of the test model were studied when passive suction and blowing rings were installed at 3 different heights of the model.The test results showed that the passive suction and blowing ring control device can effectively suppress the overall wind load and wind-induced vibration response of the high-rise building structure; the closer to the structure top the ring installed position, the more significant the wind-induced vibration control effect.
