Abstract
We conducted an experimental examination of floor vertical vibration on various movements of persons and the rubber ball impact in some floor structure. We furthermore examined the perception degree on the rubber ball impact. As a result, we got the followings: (1) The difference of the vibration response of each time is very large in the person's movement, but the difference of the vibration response of each time when the rubber ball falls is very small, (2) As for the vibration response when the rubber ball falls, correspondence with the vibration of various movement of persons is good.
