BRIDGE CONNECTING AND DAMPING STRUCTURE AND SETTING METHOD OF BRIDGE CONNECTING AND DAMPING STRUCTURE
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
【課題】隣接する橋桁同士が同じ振動特性を有する場合（固有振動数が同じ場合）においても、より効果的に適用することができる。【解決手段】隣り合う一方の第１橋桁部２に一端側を、他方の第２橋桁部３に他端側をそれぞれ接続して制振ダンパー４を設置して構成されるとともに、橋桁部２、３のそれぞれと下部構造の橋脚部７との間において、複数の支承５Ａ、５Ｂを設置するとともに、これら支承５Ａ、５Ｂのうち少なくとも一方と並列配置されるように制振装置６を設置して構成され、制振装置６として、ばね部材６Ａ又は慣性質量ダンパー６Ｂが設けられた構成の橋梁に対する連結制振構造Ａを提供する。【選択図】図１
