VIBRATION REDUCTION DEVICE OF HANGER AND STIFFENING GIRDER IN SUSPENSION BRIDGE

摘要

PURPOSE: A vibration reduction device for an auxiliary cable and a reinforcing girder of a suspension bridge is provided to simultaneously reduce horizontal vibration of a reinforcing girder and an auxiliary cable of a suspension bridge. CONSTITUTION: A vibration reduction device for an auxiliary cable and a reinforcing girder of a suspension bridge comprises a cable coupler(130), a girder coupler(150), and a connection unit(140). When the cable coupler is connected to a main cable of a suspension bridge, the cable coupler is coupled to an auxiliary cable(120). When the cable coupler is coupled to the auxiliary cable, the girder coupler is coupled to a girder unit at a position, horizontally separated from a position where the auxiliary cable is connected to the girder unit. The connection unit connects the cable coupler and the girder coupler to each other.
