小型構造物を対象とした簡易小型免震装置の応答性状

In order to investigate vibration response characteristics for simple seismic isolation system set on a small structure, vibration test have been performed. From results of excitation experiment using sine waves as input, it was indicated that the system reduced seismic response in case of the smaller friction coefficient. And the larger acceleration amplitude on input wave, isolation effects of the system indicate good performance. These effects are confirmed in case of seismic wave as input. And from results of excitation experiment set a small structure on the system, it was found that the small structure generates the rocking vibration in case of the low reduction rate on the system and overturned at the time of transient state vibration.
