Abstract: A water damping device includes a steel frame and a water-blocking cup; the device is immersed in the water and connected under the main bridge girder by wire ropes. One end of the water-blocking cup is provided with a blocking ring and a cover. The water-blocking cup cover is mounted between the cup and the blocking ring and is movably connected to the water-blocking cup. The blocking ring is used to prevent the water-blocking cup cover from opening towards the outside of the cup; an array of water-blocking cups is mounted on the steel frame along the downward direction of the water-blocking cup cover.

Abstract: Disclosed is a control method of an airbag-type intelligent control device for vortex-induced vibration of bridges. The airbag-type intelligent control device for vortex-induced vibration (VIV) of bridges includes a control system, which comprises a monitoring device and a control workstation; the monitoring device is used to detect the wind speed and direction near the bridge and the vibration state of the bridge; the control workstation is connected to the monitoring device. The VIV order of bridges is determined based on the detected wind speed, wind direction, and the vibration state of the bridge. The airbag system is mounted on both sides of the bridge and connected to the control workstation; according to the obtained VIV order, the sectional shape parameters of the airbag system are determined, and the airbag system is regulated to have the appropriate sectional shape.
