Title:
VIBRATION DISPLACEMENT SUPPRESSING STRUCTURE OF STRUCTURE GROUP
Document Type and Number:
Japanese Patent JP2019073885
Kind Code:
A
Abstract:
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 rigid body 10 that connects 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
