Wind-resisting type arch bridge arch rib
A wind-resisting type arch bridge arch rib comprises an arch rib body. A top corrugated plate is arranged above the arch rib body, a bottom corrugated plate is arranged below the arch rib body, airflow around the arch rib body is compressed by the top corrugated plate and the bottom corrugated plate to increase airflow flowing speed, the situation of vortex shedding on the downstream portion of an original arch rib is disturbed, the action of lift force on the leeward side of the arch rib body is relieved, and therefore the effect of controlling vortex-induced resonance of the arch rib body is achieved. The top corrugated plate and the bottom corrugated plate extend in the direction of the arch rib body, and the direction of corrugation of the top corrugated plate and the bottom corrugated plate is consistent with the direction of the arch rib body. Maintenance rails are arranged above the arch rib body and below the top corrugated plate. A transverse connecting structure is arranged between two branches of the arch rib body. An upper fixedly-connecting device and a lower fixedly-connecting device are arranged, and the top corrugated plate and the bottom corrugated plate are connected to the arch rib body through the upper fixedly-connecting device and the lower fixedly-connecting device respectively. The wind-resisting type arch bridge arch rib can be widely applied to half-through arch bridge arch ribs and through arch bridge arch ribs, and the influence brought by vortex-induced resonance on normal use of arch bridges is relieved.
