BRIDGE CONNECTING AND DAMPING STRUCTURE AND SETTING METHOD OF BRIDGE CONNECTING AND DAMPING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a bridge connecting and damping structure, which is effectively applicable to the case where neighboring bridge girders have the same vibration characteristics (identical characteristic frequency).SOLUTION: A bridge connecting and damping structure A has a vibration damper 4 which is installed with one end of which being connected to a first bridge girder part 2 and the other end being connected to a second bridge girder part 3, which are neighboring to each other. Plural bearings 5A and 5B are disposed between each of the bridge girder parts 2 and 3 and a bridge girder part 7 as the lower structure. A vibration control device 6 is disposed in parallel to at least one of the bearings 5A and 5B. The bridge connecting and damping structure is provided with a spring member 6A or an inertia mass damper 6B as the vibration control device 6.SELECTED DRAWING: Figure 1
