SEISMIC CONTROL DEVICE, INSTALLATION METHOD FOR THE SAME, AND WAVEFORM PLATE

摘要

PROBLEM TO BE SOLVED: To provide a seismic control device capable of improving seismic control effects by surely absorbing vibration energy independently of a high or low vibration level, whichsoever, and to provide an installation method for the same.SOLUTION: The seismic control device includes a waveform plate 21 having wavy mountains 20 alternately continuous with one another toward a first direction D1, and a constraining member 22 for holding the waveform plate 21 between both sides facing in a second direction D2 and supporting the waveform plate 21 at one end side 21a. It is provided between the superstructure and the substructure of a bridge, e.g.
