The Pacific coast of Tohoku Earthquake, damage was caused by falling ceilings. The most common countermeasure for falling ceilings is reinforcement with increased rigidity of the joints. However, there is a risk of causing an increase in the response acceleration, which could lead to a higher-than-expected seismic force input to the ceiling. Therefore, the authors propose the application of a vibration control system using block and tackle to ceilings. In this paper, the response reduction performance of the block and tackle damping mechanism at the ceiling was confirmed by shaking table experiments.
