• We investigated the intensity distribution with floor level in very tall high-rise buildings in Tokyo by means of questionnaire surveys made at the times of three earthquakes. The observed intensity value by floor tended to increase slightly with height. The plot of the intensity values with height showed a somewhat larger scatter than a plot for l4-story apartment buildings [1]. We concluded that the reason for this difference in scatter is that during floor vibration in high-rise buildings the long-period wave component predominates. We also investigated people's sense of vibration at the time of these earthquakes. Our survey clearly indicated that many people in high-rise buildings at the time of an earthquake can distinguish the existing longer period wave component in the building vibration. We also investigated the psychological state and behavior of persons in high-rise buildings subjected to earthquake motion. Results showed that people in these buildings were somewhat sensitive to building vibration.
