VIBRATION DISPLACEMENT SUPPRESSING STRUCTURE OF STRUCTURE GROUP
To realize the vibration displacement suppressing structure of a structure group that can suppress vibration displacement of a plurality of structures caused by an earthquake motion, etc.SOLUTION: The vibration displacement structure 100 of a structure group can suppress vibration displacement of a bridge pier 1 when, for example, a swing caused by an earthquake motion operates on the bridge pier 1, because the amplitude difference and phase difference between adjoining bridge piers 1 are reduced due to transmission of vibration by a pair of underground walls 10 that are joined to the footing 1b of the bridge pier 1 and connect the adjoining bridge piers 1, so that vibration of the bridge pier 1 is not amplified but is attenuated. If vibration displacement of the bridge pier 1 which is a structure can be suppressed in this way, the bridge pier 2 supported by the bridge pier 1 is less influenced by the earthquake motion, so that uneven displacement such as corner folding and unevenness may be less likely to occur in the bridge pier 2 and the number of troubles in the bridge pier 2 caused by the earthquake motion may be decreased.SELECTED DRAWING: Figure 1
【課題】地震動などに起因する複数の構造物の振動変位を抑制することができる構造物群の振動変位抑制構造を実現する。【解決手段】構造物群の振動変位抑制構造１００は、例えば、地震動による揺れが橋脚１に作用した場合、橋脚１のフーチング１ｂに接合され、隣り合う橋脚１を連結している一対の地中壁１０による振動伝達によって、隣り合う橋脚１の振動の振幅差や位相差が縮められるなどして、橋脚１の振動は増幅されることなく減衰されるので、その橋脚１の振動変位を抑制することができる。こうして、構造物である橋脚１の振動変位を抑制することができれば、橋脚１が支持している橋桁２が地震動の影響を受け難くなるので、橋桁２に角折れや目違いといった不同変位が生じ難くなり、地震動に起因して生じる橋桁２のトラブルを低減することができる。【選択図】図１
