Vibration Damping Device, Vibration Damping Method and Long-Span Bridge
Abstract The invention relates to the technical field of bridge vibration damping, and discloses a vibration damping device, a vibration damping method and a long-span bridge. The long-span bridge comprises: a plurality of piers arranged at intervals, each of which is provided with a cross beam; and a main beam, which is arranged on all the cross beams; wherein each pier is provided with one vibration damping device or two symmetrically arranged vibration damping devices. Each main beam vibration damping device comprises: a dowel bar, one end of which is rotatably connected with the bottom of the main beam outside the pier; an amplifying rod, whose middle part is rotatably arranged on the cross beam or the pier, comprising a connecting end and an amplifying end, and the connecting end is rotatably connected with the other end of the dowel bar; and a damper, one end of which is relatively rotatably arranged on the cross beam or the pier, and the other end is rotatably connected with the amplifying end. The vibration damping device can solve the problems of wind vibration and vehicle vibration, including vortex-induced vibration, of long-span bridges in the prior art under specific wind speed.
