KURAJI KENTARO / ONISHI TAKANORI / ISODA KAZUHIKO / WAKAHARA TOSHIHIRO

PROBLEM TO BE SOLVED: To provide a connected vibration control structure for a bridge, which enables vibration control to reliably and effectively improve earthquake performance of the bridge by properly setting specifications of a vibration control damper installed in such a manner as to connect adjacent bridge girder parts of the bridge, and a setting method for the connected vibration control structure for the bridge.SOLUTION: A connected vibration control structure A for a bridge is configured by installing a vibration control damper 4 in such a manner as to connect the side of one end to one girder part 2 of adjacent bridge girder parts and connect the side of the other end to the other bridge girder part 3.SELECTED DRAWING: Figure 1

【課題】橋梁の隣接する橋桁部同士を連結するように設置する制振ダンパーの諸元を適正に設定し、制振によって確実且つ効果的に橋梁の耐震性能を向上させることを可能にする橋梁に対する連結制振構造及び橋梁に対する連結制振構造の設定方法を提供する。【解決手段】隣り合う一方の橋桁部２に一端側を、他方の橋桁部３に他端側をそれぞれ接続して制振ダンパー４を設置して橋梁に対する連結制振構造Ａを構成する。【選択図】図１
