PROBLEM TO BE SOLVED: To provide a vibration control structure of parallel bridges, capable of exerting vibration control of the parallel bridges by a simple structure without large-scale structural change and obtaining reliably high wind resistant stability. SOLUTION: In a vibration control structure which is provided in parallel bridges constructed by constructing a plurality of bridges 1, 2 in parallel in the width direction and suppresses aerodynamic vibration of the parallel bridges, flat plate-like rectification means 3 is formed in a long size in a bridge axial direction of the bridges 1, 2 and disposed over the width direction in a clearance 100 between the superstructures of the adjoining bridges 1, 2. The rectification means 3 is structurally connected to at least one of the superstructures of the adjoining bridges 1, 2. COPYRIGHT: (C)2012,JPO&INPIT |
