解析と測定に基づいた床振動に及ぼす間仕切壁の影響に関する考察

In this study, the effects of partition walls on floor vibration were discussed based on analysis and measurement. Vibration measurements before and after removal of partition walls showed significant differences in response and vibration characteristics. The analysis showed that the effects of the partition walls depend on the vibration modes of the upper and lower floors where the partition walls are attached. It was inferred that partition walls have the effects of increasing effective mass due to the mode change and increasing stiffness due to the resistance elements of the floor, depending on the phase of the connected floors.
