ナイロンテグスを用いた文化財固定の転倒防止効果

抄録

In order to establish an overturning prevention method of cultural properties fixed by nylon guts due to seismic ground motion, we obtained the overturning rate of specimen by vibration test and investigated the effectiveness of overturning prevention based on it. Peak acceleration amplitude of input waves, in case of 1995 Kobe earthquake, 2003 Niigata earthquake and 2016 Kumamoto earthquake, that is overturned the specimen fixed by nylon guts was around 4.5 times higher than without fixed one. Since the overturn of the specimen fixed by nylon guts has been due to sliding at the bottom of specimen, it is better to increase the friction coefficient at the surface of display table. Then it expects to improve overturning prevention.
